Domain controller

Yes, in a mixed mode environment which is the default for a Win2k Domain. I do believe though that a Win2k DC can only act as a PDC emulator in a Win2K domain.

You'd have to upgrade a NT PDC to Windows 2000 Server. The Win2k DC will act as the PDC and repackage the directory information for downlevel replication to your NT BDC's.

It would be wise to disconnect a BDC from the network so that in the case of a failure, you have a server ready to promote with a recent copy of your SAM database. Not to mention backing up your PDC ;-)

Hope this helps,

The bottom line is this:

1. Win2K domain controllers CANNOT exist in an NT4 domain.
2. Win2K member servers (non-domain controllers) CAN exist in an NT4 domain.
3. NT4 BDCs (but not PDCs) CAN exist in a Win2K mixed-mode domain.

Hope this helps.
