Currently I'm running on AD environment with one Win2k3 domain controller, 4 Win2K domain controllers and 1 NT 4.0 (SP6) BDC. At the moment, when I try to use the User Manager for domain at the NT 4 BDC, the windows pop up "Cannot find Domain Controller for this domain" appear.I can select the domain but still cannot connect to it.
1. Since the nt 4 BDC is not critical anymore to me (all sharing, WINS etc function was transferred to another server), I plan to remove it from the domain.Can I just remove it manually using Win 2000 Adsi edit tool and after that change the environment to Native Mode. (Assuming the nt 4 BDC is no longer functioning due to hardware failure)
2. When opening the user properties from AD users and computers, at the Account tab, I found the user logon name is blank for some users. I beleive this is due to that users is created in the Win NT 4.0 environment. For newly created users (AD environment) there is no problem, they have both userlogon name and pre windows 2000 username created. Is that any impact if I just change from mixed to native mode without manully key in the userlogon name for those related users.
