Error message when you run the Dcgpofix.exe tool on a Windows Server 2008-based domain controller: "The Active Directory schema version for this domain and the version for this tool do not match"

This problem occurs because the Dcgpofix.exe tool uses a schema check to make sure that the correct behavior occurs. The correct behavior depends on the schema version of the Active Directory schema. When the Dcgpofix.exe tool does not correctly check the schema version of the Active Directory schema, this problem occurs.
