Verifying Exchange 2007 sp1 Schema Extensions

Exchange 2007 sp1 is in beta 2 available in TechNet and MSDN. The download is over 750MB. This is because sp1 is already streamlined into Exchange 2007 RTM. This is an important for installing on Windows 2008, which will require sp1.

Whether you run service pack 1 setup.exe (the graphic interface) or setup.com (the command line powertool) with /PrepareSchema or /PrepareAD, it needs to further extend the Active Directory Schema. To confirm that the schema extension was successful, we use ADSIEdit to peer into a Schema Version attribute.

E2k7sp1b2_schema_vers_pt_2

In ADSIEdit (part of the Windows 200x support tools install) expand the Schema Configuration container. In the right pane, navigate down to CN=ms-Exch-Schema-Version-Pt. Double-click on that to list its attributes. In the Attribute Editor tab, scroll down to the rangeUpper attribute. If Exchange 2007 Service Pack 1 beta 2 has successfully extended the schema, then this value should read 11116.

This value for the RTM version of Exchange 2007 read 10637. For Exchange 2003, this read 6870. And Exchange 2000 returned a value of 4397.

exchange server 2007 relation information

Posted by: suhas at Sep 28, 2007 9:33:15 PM

I'm running a Parent and Child environment. I'm preparing my AD for Exchange 2007 on a 2008 Server. The /prepareschema was run in the Parent domain as it holds the Schema. My Forest is at 2003. I'm currently running Exchange 2003 in the Child domain. After running the /prepareschema and checked the adsiedit, I'm still showing a rangeupper value of 6870. Am I doing something wrong?
