Have you ever had one of those jobs where you just weren’t sure what Schema update had been applied in an environment? The following command will let you know which of the Windows Server Schema updates have been applied.
dsquery.exe * “CN=Schema,CN=Configuration,DC=domain,DC=com” -scope base -attr objectversion
Here is what the versions will mean:
44 = Windows Server 2008
31 = Windows Server 2003 R2
30 = Windows Server 2003
13 = Windows 2000
If anyone knows the Exchange Schema update numbers please post and share.
