Thanks Eric
We have 2 other BDC's, so we are covered in event of a failure. I noticed
that even though I added the machine as a BDC, it appeared as a Windows NT
5.0 Server after the domain synchronized. So, things may have taken care
of themselves. I've noticed some slowness when trying to add printers,
over a minute for the Printer wizard to display what's on the network, but
overall traffic seems to be otherwise manageable.
