A new version of the Active Directory management pack is available for download at Microsoft Connect webpage. This updated version of the AD MP addresses several issues in the original AD MP that shipped with RC2.  Specifically it fixes:

• AD Topology Discovery
• Discovery of DCs with non-US locales
• Discovery of Windows Server 2000 DCs
• Fixed problem: Defect: AD MP for Windows Server 2000/2003 – local discovery of the Domain Controller fails if targeted DC is using a non-US date/time/number format 
• Fixed problem: Defect: AD MP for Windows Server 2000 (all locales – under certain conditions)
