When extending Win2K AD Schema choose ADAM

Believe it or not some companies are still using Windows 2000 out there. I had an issue the other day trying to extend the AD Schema for TAM ESSO and it failed trying to add the v-Go classes. Attributes were added just fine, but the classes would not get added to AD and all I got was a meaningless error message. Choosing ADAM as the Repository Type seems to work fine. I know that choosing Microsoft Active Directory as the Repository Type works for Windows 2003. Maybe it's just a Win2K thing. Hey whatever works.
