We upgraded our PDC to Win2k and it's running DNS. The DHCP server is still an NT 4.0 server. When I reboot my Win2k client and do a 'echo %logonserver% it tells me that the logon server is one of our NT 4.0 BDC's that was a PDC then demoted to BDC prior to the upgrade. Why would my 2k client not get validated by the Win2k server?
