SID error on cloned Virtual Server / VPC / VMWare OSes

If you simply copy an existing Windows OS image to create multiple virtual servers/workstations, and try to log on to a domain controller, you may get the following error: The system or security ID (SID) of the domain specified is inconsistent with the trust information for that domain.

Exchange SP2 – Connection Filtering that actually works

I was excited to find out about Connection Filtering (screenshot) in Exchange 2003 – finally I could use RBLs (real-time block lists) without having to dabble with event sinks!!

Message Tracking as part of OWA/Outlook

Message Tracking is one thing I’ve since long wanted to see built into the client – either as an OWA-only feature or perhaps in OWA and Outlook.
