  • Does SP1 for Windows Server 2008 R2 change the schema version? I noticed that the schema version does increase when going from non-R2 to R2 in both WIndows Server 2003 and 2008. Thanks.

  • No it does not.

  • The objectVersion attribute will display <not set> on any DC other than the schema FSMO role holder in ADUC and/or ADSI Editor...
