Big Domain Problem....

By omarhib ·
Hello There,
I have a big problem with the domain at the company that i work in,,,
This is my first month with the company and in less than 10 days the domain failed 2 times.

The first tme we had 1 dc and i failed, and displayed a message that it couldn't fond the global catalog for the domain.

The next day i found that the domain is working and i promoted another domain controller and made it the Global catalog and DNS server in addition to the other DNS server we already have.
i've cleared the Global catalog check box for the first DC, and it worked and the replication between the two DCs went great. Now after 5 days the two domain controllers failed and it displays a red X in the Active directory Users and Computers and in the Active directory Sites and Services.
None of the employees can logon to the domain, and we are now having a big problem...

All of the servers are Win2k Server and all the clients are WinXP.

Now what would be the cause of this problem and what would be the possible solutions to get ar least one domain to life and with the least possible effort??

Thanx in advance.

Look in the Event Viewer esp. the Directory Services log. Also, check DNS and Logon (lsass.exe) services are running.
Use Netdiag and Dcdiag tools to troubleshoot the problem.

As a last resort, restore the System State back onto one of the DCs to restore the domain.

Do u run any AV software on servers (DC)?
I had similar problem when I had Sophos AV installed on DC. After removal of Sophos AV, there are no more domain failures

hi there

i have personaly faced the same problem with my WinXP clients falling to locate the domain. i had 3 client computers with WinXP and every now and then they fail authontication from the domain and will not be able to access network resouces.

this could be caused by one or two reasons. if you are using Win2k mixed mode, you dont have the capability to support WinXP Clients smoothly, Win XP creats some sort of a firewall and you will not access network resources.
however Win2K DC and Win2003 support that

you could go around this problem by introdusing a Win2003 DC, i will work perfectyly well with WinXP.

as for my case, i made sure all my clints are Win2k and i have never had that problem again.

hope this helps.
