Am upgrading win9x machines to XP. All is well, until I click that "this machine is part of a domain". Then a box prompts for username/pwd of someone with permissions to join this computer to domain. It won't take my account. I am not a network administrator, but have joined many Win2000 machines to the same (Win2000) domain. Am told there is a security feature (or glitch) in NT, etc that restricts a user to only joining 10 machines, and that I must use another user's account. I have access to many with domain permissions, have tried 7 or 8, without success. End result is "access denied". Am getting run-around from Network services. Have many new XP machines about to arrive. Without a "fix", cannot login to Domain. Help!
