One morning, I cannot log on to the domain. All clients cannot logon. Netlogon is not working so I cannot use mapped drives. I cannot run tool like DCdiag. Event viewer - Event ID 13516 - FRS (File replication service) is no longer preventing the computer... from becoming a domain controller. I specify the ports, but client still cannot logon. Event viewer does not show any problem.
Any ideas...
:confused:
