I have 2 NT4 domain controllers and a SUN V880 running PC Netlink as a domain controller. My issue is this: My NT4 domain controllers are also running ScriptLogic which is a great tool for running scripts, mapping drives, etc.. ScriptLogic does not work with the SUN. So, what I need to know is how can I force my clients to use one of the NT4 controllers and never the sun to logon?
