Got Win2003 Adminpak on XP and don't see the Dial-In tab..

Adminpak installed on XP Pro does not reveal the Dial-In tab on user's properties.

Here's how to make it show up :
Registry Entries - copy the following text in notepad and save as dialin.REG (don't forget to change file type drop-down to All):

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\RasDialin.UserAdminExt]
@=""

[HKEY_CLASSES_ROOT\RasDialin.UserAdminExt\CLSID]
@="{B52C1E50-1DD2-11D1-BC43-00C04FC31FD3}"

[HKEY_CLASSES_ROOT\RasDialin.UserAdminExt.1]
@=""

[HKEY_CLASSES_ROOT\RasDialin.UserAdminExt.1\CLSID]
@="{B52C1E50-1DD2-11D1-BC43-00C04FC31FD3}"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MMC\NodeTypes\{19195a5b-6da0-11d0-afd3-00c04fd930c9}\Extensions\NameSpace]
"{B52C1E50-1DD2-11D1-BC43-00C04FC31FD3}"="RAS Dialin - User Node Extension"

Then double-click the file or on command prompt type :
Regedit /s dialin.reg

Type the following commands - replace ServerName with a Windows Server 2003 domain controller:
cd /d %SystemRoot%\System32
copy \\ServerName\Admin$\System32\mprsnap.dll *.*
copy \\ServerName\Admin$\System32\rasuser.dll *.*
copy \\ServerName\Admin$\System32\rtrfiltr.dll *.*
regsvr32 rasuser.dll

Now open AD Users & Computers console and check a user's properties. The Dial-In tab should be there.
