We are running Zfd 7 on Win2K & XP desktops and trying to migrate from a collection of NW6.0 servers to new NW6.5 systems. Whenever we disable logins on one of the old servers that held master replicas of all of our partitions, some workstations have problems logging in. Specifically, the user gets a second login asking for local workstation credentials. If we reenable logins on the old DS server, the problem goes away. Any ideas?
