Exchangepedia turns 4!

Posted by Bharat Suneja at 11:00 AM
Yes, Exchangepedia Blog is 4 years old today! Exchangepedia saw its first posts in June 2004. Hundreds of posts, 1 major Exchange release and 2 service packs (Exchange Server 2003 SP2 and Exchange Server 2007 SP1) later, it's great to look back at some of the stuff I've enjoyed writing, and some posts that got great feedback.

Exchangepedia turns 4

Feedback about the content and other aspects of Exchangepedia is always welcome and valued. Sorry, I'm unable to reply to each comment and cannot respond to each question, I do read all of them.

With that in mind, if you have any feedback on the posts, screenshots, "screencasts", scripts, design, content, topics, etc., please leave a comment.

- Has it been useful for you?
- Is it interesting to read?
- Do the posts here help you resolve any deployment/operations issues or clarify a concept?
- Are there additional topics you'd like to see covered here?
- Would you like to see any changes to anything on the blog - the content, the design, anything? (Except for adding a Search box, which is on the top of my list... )?

In the 5th year of its existence, I do intend to finally move Exchangepedia off the Blogger platform, and no— it being a Google product really has nothing to do with it. I love Wordpress, and would like to play with Joomla! or Community Server as well— time permitting. Migrating all the content, comments, and keeping existing URLs is a bigger and more complicated project than I thought.

Finally, the traffic has been rising steadily, and the existing server that's been hosting this blog since day 1 seems to be limiting. I would really love to move off the 400-Mhz. Pentium 3 box that's been serving this site (and quite a few other web sites, including some Wordpress ones)— maybe to a Windows Server 2008 web server running inside a Hyper-V virtual machine. If my tests with Wordpress on Windows 2008 go well, I will hopefully be able to do that soon.

Meanwhile, if you know of a "Migrate This" button I can click on to migrate all posts, comments and URLs from Blogger to Wordpress, please email me!

Windows Server 2008's new Windows Server Backup utility, the replacement for NTBackup, doesn't do Exchange backups out of the box.

I'm in Scott Schnoll's session where he just announced a new Microsoft plug-in that will do Exchange VSS backups. The tool will be released this summer.

More notes from this excellent session soon!

Exchange Server 2007: The Complete Reference started shipping recently. (OK, it's been a few weeks, so I'm stretching the definition of the word "recently" to cover up for the fact that I didn't post about this sooner...)

As Exchange MVP and coauthor Richard Luckett puts it, "Writing a book, sustaining a career, and spending precious time with family are all desirable goals, but difficult to manage all at once. Over the last year and a half of writing this book, I have stretched the boundaries of all my personal and professional relationships". I couldn't agree more!

McGraw Hill has a book signing today at the Digital Guru bookstore at TechEd. Richard and I will be present. Exchange MVP William Lefkovics plays the missing coauthor role.

What: Book Signing - Exchange Server 2007: The Complete Reference
Where: Digital Guru bookstore at TechEd IT Pro 2008
When: 4:15-4:30 PM today (June 10, 2008)

If you're at TechEd, stop by and say Hi! If you can't make to the book signing, you will find me at the Exchange Server booth all mornings.

Zenprise Wins Best Of TechEd 2007 Award

Posted by Bharat Suneja at 5:32 PM
An interesting week in Orlando, as TechEd weeks generally are. The Zenprise team returned home with the Best of TechEd 2007 award! That's 2 years in a row - first time a start-up has won Best Of TechEd two years in a row! What's a cause for cheer for most of us - this time it's in the Mobility category, for Zenprise for BlackBerry! (Last year, Zenprise for Exchange won the Best of TechEd in the Messaging category - read previous post "Zenprise wins Best Of TechEd 2006 award").

It was great to see customers visibly excited about Zenprise for BlackBerry, and the new User Dashboard feature in Zenprise 3.1 (in beta right now, this is what attendees saw at our TechEd booth last week) promises to make the job of IT/messaging/mobility help desks a lot easier. For Exchange, the User Dashboard provides a quick snapshot of all the important user properties and real-time performance stats of a user's mailbox server. For BlackBerry, the User Dashboard shows BlackBerry Enterprise Server and BlackBerry device-related properties and performance stats, and also an end-to-end availability state for a particular user. The dashboard also enables instant testing of a user's device.

The rapid-fire software release cycles of our times means we're working on some exciting new features for v3.2, in our mission to go where no Exchange and BlackBerry monitoring & troubleshooting products have gone before. :)

Tuesday night was a Birds of a Feather (BOF) night, with plenty of BOF sessions and chalk talks scheduled. My session on Fighting Spam With Exchange Server 2007 (not a very creative title, I know... but it got the message across :) was scheduled for 7:45 PM. I was positive I'll probably be the only person in the room - 7:45 PM isn't exactly the time I'd want to attend a TechEd session on anything, with the exception of a few good speakers.

On a side note, keeping my expectations low also meant I could claim the attendance was more than I expected even if only one person showed up. Nevertheless, the room filled up as we got closer to the start time.

It was an interesting discussion on anti-spam in Exchange Server 2007, as well as Exchange 2003.

Some takeaways:

  • Exchange's anti-spam features consist of more than just Intelligent Message Filter (IMF) - there's 1) Connection Filter: allows using IP Allow Lists, IP Block Lists, IP Block List Providers (RBLs) and IP Allow List Providers 2) Sender Filter: block sending domain or SMTP address 3) Recipient Filter: block internet messages to list of valid recipients, perform Recipient Validation to block messages for non-existent recipients 4) Sender ID Filter: looks up SPF records in purported sending domain's DNS zone, protects from address spoofing and phishing 5) Content Filter (aka "IMF"): Blocks messages based on content
  • 3 Gateway Thresholds and Actions: Exchange Server 2007's Content Filter Agent supports 3 gateway thresholds and actions - 1) Delete 2) Reject and 3) Quarantine
  • Quarantine functionality: Though the quarantine functionality in Exchange Server 2007 is a step forward compared to Exchange Server 2003's archiving feature, it's not as full-featured as that offered by many third-party products. End-users have no control over the quarantine - an administrator has to inspect quarantined messages and make the decision to deliver or delete. However, it's important to understand that a) it's not compulsory to use the quarantine and b) The end-user mechanism for accessing suspicious messages is the Junk Mail folder c) Quarantining is one more layer available to admins - between the gateway actions of Rejecting or Deleting mail and the Store action of delivering to Junk Mail
  • Exchange Server 2007's Connection Filter agent does not immediately drop connections from IP addresses explicitly listed on the IP Block List. Exchange Server 2003 does this for IPs listed in its Global Deny List. This change in behaviour allows such "filtered" connections to be logged in the agent log. Some customers like to see these logged, whereas many want connections to be dropped immediately.
  • Many customers prefer anti-spam appliances like Barracuda and IronPort in the perimeter, and consider these very effective, and generally lower cost compared to an Exchange 2007 Edge Transport server.
  • No studies or test results are available yet to demonstrate how the Edge Transport server performs compared to such appliances. It would be great to have a feature and performance comparison of these.
  • Many customers are interested in Greylisting - a technique that registers each connection's "triplet" of a) Sending host's IP address b) Sender's address c) Recipient's address and looks up a database. If not found, the connection is immediately dropped and the triplet added to the database. The technique is based on the idea that valid RFC-compliant SMTP hosts will attempt to resend the message after a set interval. The (receiving) SMTP server will find the triplet in the database upon the second attempt, and consequently accept the connection.
  • Interested in learning more about Greylisting? Evan Harris has a whitepaper titled "The Next Step in Spam Control: Greylisting"
  • Exchange Server 2007 SDK has the code for a Greylisting agent. This needs to be compiled into a DLL using Visual Studio 2005, and installed using the accompanying installation script. Since this is just a programming sample provided in the SDK, it makes sense to test this adequately in a test environment and not expect any production support
  • Freeware Greylisting transport sinks/add-ins for Exchange Server 2003 are available on the web, like this one from Chris on Grynx.com
  • Over a period of time, the effectiveness of techniques like Greylisting may decrease, but as of now it still eliminates 80-90% of spam.
  • SMTP Tarpitting is a technique that inserts a delay in SMTP responses to SMTP clients that display suspicious protocol behavior. More details about tarpitting in a previous post titled "Enabled by default: SMTP Tarpit in Exchange Server 2007"
  • Safelist Aggregation: This allows Exchange to aggregate senders marked as safe by (Outlook/OWA) users. If an EdgeSync subscription exists (in topologies with an Edge server), the safe list is replicated to the Edge as part of EdgeSync. Exchange's use of safe lists can reduce false positives significantly. It's not required to have an Edge server - Hub Transport servers with anti-spam agents installed can also use this feature.

If you're going to be at Microsoft TechEd 2007 in Orlando next week, and are interested in sharing your experiences in fighting spam using Exchange Server's anti-spam features, here's a Birds-of-a-feather (BOF) session just for you.

What: BOF session "Fighting Spam With Exchange Server 2007"
When: Tuesday, June 5th @ 7:45 PM
Where: Microsoft TechEd, Orlando, FL
What's a BOF session? : Birds-of-a-feather sessions are not presentations or lectures. These are meant to be interactive discussions, sans the PowerPoint slides and demos you typically see in breakout sessions.
Why so late?: Tuesday night is an all-BOF session night, with no other conference activities. Microsoft will be serving food and drinks.

“Exchange Server 2007 anti-spam features are a significant improvement over previous versions, and come with interesting deployment and topology questions. Are these effective in the fight against spam? This BOF session will be a round table for Exchange administrators to talk about their experiences with Exchange Server 2007 anti-spam features, including issues such as Edge servers, use of IP Block List Providers, and new features and techniques such as Sender Reputation, and Safelist Aggregation.”
Audience: IT Professional

At Exchange Connections, Orlando

Posted by Bharat Suneja at 9:38 PM
Arrived in Orlando earlier this morning. After last week's tiring trip to this city for TechMentor, and having my laptop being lost/stolen on the way back (a painful story of Delta Airlines misrouting my luggage - yes, one of those occassions when I ended up checking in all my luggage including the laptop bag, recieving 1 out of 2 bags, getting the second one couple of days later with the laptop missing! If you see a Dell Latitude 610 with an Exchange Server 2007 sticker on the lid... nevermind, perhaps that's wishful thinking...), I'm already travel-weary.

Nevertheless, I've been looking forward to Exchange Connections.

If you're here, do stop by and say hi - I'll be at the Zenprise booth.

TechEd 2007: Looking for another venue?

Posted by Bharat Suneja at 3:34 PM
In Vegas I learnt Microsoft is moving TechEd 2007 from New Orleans - the venue announced and publicized earlier. Redmondmag.com has more on this today - Microsoft is citing logistics issues of moving (an estimated 14-15,000 people, including 11,000 attendees) in and out of the city.

A new venue has not been announced so far, but one can be sure it was selected before the move out of New Orleans was announced. (In the limited time and internet access I had, I tried looking for a PR on Microsoft's web site but couldn't find one).

After travelling to the east coast for 2 years in a row (Orlando in 2005, and Boston this year), I would love to see it on the west coast next year. My top venue choices for the event: 1) San Diego 2) San Francisco 3) Seattle.

Posted by Bharat Suneja at 7:27 PM
I'm in Las Vegas for TechMentor conference - organized by 101 Communications, the publisher of Redmond magazine (formerly MCP Mag), and CertCities.com web site.

All Exchange sessions at TechMentor are being presented by Zenprise folks this year. If you're attending, don't miss out on the Exchange track - sessions are listed here. (If you're not attending the sessions, feel free to walk up and say hi to me at the Zenprise booth.. ).

I'm presenting the following:
Monday Oct. 9 - 12:30 AM - 2:00 PM: Overview of Exchange 2007
Also on Monday - 2:15 - 3:45 PM: Messaging Hygiene in Exchange 2003 and Beyond

Also on Tuesday 10:15 AM - 11:45 AM: Clustering Exchange with Exchange Server 2003 (includes brief overview of clustering in Exchange 2007 as well)


Monday, July 17, 2006

I am playing the "Featured Expert" for TechTarget's ExpertAnswerCenter.com web site for the next 2 weeks starting today. I will be answering questions from users/visitors, and blogging on their web site - the first blog post talks about some of the changes we'll be looking at now that Exchange Server 2007 Beta 2 is just around the corner.

If you haven't pre-registered for Beta 2 yet, now would be a good time to get that done.

The Exchange team blog has seen plenty of Exchange Server 2007 content in the past few weeks, beginnng shortly before TechEd. Now you can see many PMs candidly talking about the new features in a series of videos shot during TechEd - when you see the volume of content go up dramatically you know Beta 2 is really here... ! :)

Zenprise wins Best Of TechEd 2006 award

Posted by Bharat Suneja at 4:25 PM

The Zenprise team returned from TechEd last week with some exciting news - Zenprise 2.0 was awarded the Best of TechEd 2006 in Messaging category by Windows IT Pro magazine! [Windows IT Media Names 'Best of Tech Ed 2006' Winners ] We're all very excited about this, as it comes close on the heels of several other events that I've blogged about recently, notably:

- Zenprise named one of the Top 15 Tech Startups To Watch by InfoWorld magazine
- Zenprise named finalist in SIIA's Codie Awards
- A big thumbs up by InfoWorld in their Exchange management product reviews (v1.03)

From Michael Otey, Technical Director of Windows IT Pro:
"Zenprise provides a powerful automated email problem resolution solution that collects operational data from across the entire Exchange infrastructure. It constructs a baseline profile showing typical system activity and performance levels and automatically analyzes deviations from these baselines, matching the symptoms against possible causes. The product then provides a series of steps that the administrator can follow to resolve the problem".

Other finalists in the Messaging category: Research In Motion's Blackberry Enterprise Server, and Quest Spotlight on Exchange.

Looking back, it's hard to believe we didn't have a released product at TechEd last year... we released Zenprise 2.0 (yes, there were versions 1.x before this.... :-) at TechEd this year!

Dell laptops don't have wireless access at TechEd!

Posted by Bharat Suneja at 8:32 PM
I've enjoyed TechEd throughout this week - some great sessions I've been to, and all the folks I've been meeting all week - MCTs, MVPs, softies... and the parties have been great so far.

The one thing that's really been annoying me is the fact that my Dell Latitude D610 running XP SP2 can't connect to the wireless network at TechEd. My laptop sees the TechEd wireless network as a computer-to-computer (peer) network, and doesn't get an IP address.

Of course, being the busy week that it has been, I really haven't had the time to work on troubleshooting it beyond what I already know about Windows, networking, and wireless networks - and I know this stuff fairly well (yes, I'm being modest here... :)

Having confirmed it with a few other attendees, I can confirm the problem is being faced by folks with Dell laptops. I'm not completely sure if others with different brands of laptops are facing this problem as well, but the ones with Dells certainly are....

.... and Dell isn't present on the trade show floor - as far as I know, they haven't been participating in TechEd since last year in Orlando.

Not sure if there's a firmware upgrade that needs to be applied, but it's pathetic to see all these people with Dell laptops unable to connect to the network.

I ended up using my new Moto Q windows mobile phone to access the web. I haven't posted a review of what I think about the Moto Q so far, because it's all negative and I really try to avoid posting negative feedback about a vendor or a product.... but I will most likely end up posting something about the Q since I endured being without a cell phone for weeks just so I could get a Q.

Needless to say, accessing the web with a mobile phone - no matter the screen size, which isn't as large as the Moto Q commercials make you think... - and no matter what the speed is - which also isn't too great on the Verizon network imo - mobile phones are really no substitutes for laptops.

Perhaps I have a new ultra-mobile windows device in my future!


Tuesday, June 13, 2006

Just got out of a breakout session titled "Microsoft Exchange Server 2007: Management Shell and Scripting" by Vivek Sharma & Mihai Jalobeanu. Vivek & Mihai provided a great technical deep dive into Powershell (aka "Monad") and how to use Exchange Management Shell (a layer on top of PowerShell) to manage Exchange Server 2007.

The session was full of demos, and if you weren't following PowerShell and Exchange Server 2007 for a while some of those would've made your jaws drop!

At the same time, it's important to note that this command-line management functionality does not come at the cost of GUI tools. A good part of what can be done from the shell can also be accomplished from the GUI - but for a lot of repetitive tasks the shell is simply way more efficient. Some advanced tasks will only be possible through the shell (just as some more advanced functionality is only available through registry hacks).

If you're interested in Exchange, it'd help to get a leg up on PowerShell and Exchange Management Shell (again, EMS is a layer on top of PowerShell - not a different beast... ) as soon as you can.

I'm heading to Boston tomorrow to attend Microsoft TechEd. Look forward to meeting friends, peers, MVPs, MCTs, Zenprise customers, and "softies"... !

As noted earlier, Zenprise architect Sekou Page will be presenting a Birds Of A Feather session on troubleshooting DNS for Exchange. (read previous post: "Don't miss "Troubleshooting DNS for Exchange" session at TechEd").

Trying to figure out which other sessions you should consider attending? Experts at TechTarget (publishers of popular sites like SearchExchange.com, SearchWindowsSecurity.com, SearchSQLServer.com, et al) have picked some interesting ones - you can find them at "TechEd 2006 Best Session Picks" - includes some of my picks.

Clustering MVP Rodney Fournier will be presenting 2 sessions, and knowing Rod I'm sure they'll be quite interesting and geeky.
1. SVR317 The Best-of-the-Best Practices for Microsoft Clustering, and a Few You Haven't Heard of - But Should
- Wednesay June 14, 8:30 - 9:45 AM, Room: Grand Ballroom B

Zenprise will be at Booth #245 (TechEd Expo Map). If you're at TechEd, don't forget to drop by and say hi, and also take a shot at the Zenprise Exchange Challenge(s) to win some great prizes, including some cool (marketing-speak? Naah, I want one myself... ) MyVu personal video viewers - particularly a gread add-on if you have a video iPod. You will also get a chance to take a look at our latest & greatest Zenprise 2.0 product for real-time troubleshooting & diagnostics of Exchange.


Wednesday, May 24, 2006

Another year goes by, and TechEd 2006 is already here! If you're going to be in Boston next month, as a TechEd attendee you'll have a long list of sessions to pick from, with more than a few sessions you're interested in being scheduled at the same time.

I've always faced this huge dilemma of choosing which sessions I want to devote my time (definitely a scarcer resource during TechEd) to.

Zenprise architect Sekou Page will be presenting a Birds of a Feather session titled: Troubleshooting DNS for Exchange: Confronting The "Black Box". Sekou is a principal Exchange knowledge architect at Zenprise, with plenty of infrastructure experience and over 50 Exchange migrations to his credit. He writes a column for Redmond magazine.

If you work with Exchange and DNS, this should be one of the interesting sessions to look forward to at TechEd.

Session Abstract:
Troubleshooting DNS for Exchange: Confronting The "Black Box"
Thursday, June 15, 11:45 AM - 1:00 PM
DNS is often considered a "black box". That is, once configured and working it is hard to figure out why it "breaks" or what might be wrong in a deployment where the service should be fully functional. The focus of this session is - how to troubleshoot DNS issues as they relate to email - specifically, Microsoft Exchange. This session will share in a group discussion on DNS and the core components of DNS and the approaches one should take when troubleshooting specific classes of issues: including connectivity, zone integrity, performance, Active Directory DNS and name resolution. So, by thoroughly understanding the different classes of DNS issues and the troubleshooting process required to approach a specific type of issue, DNS will no longer be considered the "black box" it once was.
Session Type(s): Birds of a Feather
