I was recently getting an error when opening AD users and computers - Naming information cannot be located because: Logon attempt failed. Contact your system administrator to verify that your domain is properly configured and is currently online."
I was told to issue these commands to solve the problem:
secedit /configure /cfg %systemroot%\repair\secsetup.inf /db secsetup.sdb
secedit /configure /cfg %systemroot%\repair\secdc.inf /db secdc.sdb
What exactly will these commands do?
