I've renamed and deleted the administrator account on a Windows 2000 domain controller (oops) and now I can no longer open Domain Controller Security Policy, Domain Security Policy or the Local Security Policy from Administrative Tools. I can open Active Directory Users and Computers and right-click on Domain Controllers, click on properties, click on Group Policy, click on Default Domain Controllers Policy and click Edit. However, if I make a change to the User Rights Assignment, it isn't actually applied on the Domain Controller. Is there anything that I can do to get the Local Security policy back? I've already tried using MMC Security Configuration and Analysis snap-in, but it gives me an error message when I try to import a security template about an extended error. Anybody have any ideas?
