I am currentlly attempting to run the inetorgperson fix on an existing Server 2000/Exchange 2000 AD environment in preparation to introduce Server 2003 and Exchange 2007. Before I run adprep from Server 2003 disk, my research in the issue discusses running this fix. However, when i run it, i am getting errors on the Exchange.ldf, Inetorgperson.ldf files within the kit. I get the error that the registry key is not set or this DC is not a schema master. I know its the schema master, as i have checked this prior to starting this project. Also this is the only DC in this AD domain. It holds all FSMO roles. I cannot seem to find any documentation on TS this issue. Any help would be greatly appreciated.
