44 = Windows Server 2008
31 = Windows Server 2003 R2
30 = Windows Server 2003
13 = Windows 2000

To check the domain schema version:

dsquery * cn=ActiveDirectoryUpdate,cn=DomainUpdates,cn=System,dc=domain,dc=local -scope base -attr revision

The command will return the revision of the Active Directory update:
