[Rooky]

Hi everybody, I have a domain controller with Windows 2003 Server and something happended with the security that was violated and now my server has block the network and is impossible to authenticate all the users. Is there a way to unblock my server?

First, check if firewall on DC is disabled.
Probably accidentally somebody turn on fireall...

Hi Rooky,

I guess by now you have already checked if these services are started:
Netlogon
Server
Workstation

Hope it helps.

Hi guys and thanks for your quick reply,
I note that the problem was related to a malfunction of the hard disk. When I got to work this morning I noticed that the server showed an error reading, so I imagine that this error was because the hard disc was about to die.
Thanks again!

I have found my problem already. Thanks everybody.
