PDC not on in the Domain

By boikanyo.geo ·
A PDC for an NT domain has been running fine until it was rebooted on the 11th July 2000.

The server was rebooted at 11:03am. When it came up, It was looking for a trusted domain and could not locate it.No User could see the PDC and the PDC couldnot see any other pc on the network.
I have done troubleshooting and consulted MS technet! no answer to this problem yet!

Further, the server manager has all PC's greyed out. If you select to see ALL and "Show Member of the Domain Only", The PDCdisappears and only the greyed pc remain.

PLEASE HELP!!!!!

I can't tell why it happen, but I have an idea you can try. Select a BDC that it's not greyout and promote it to PDC, reboot (if you can) each BDC (leave the PDC off), once you're done, Syncronize the network. Now allow, 15 minutes for the syncronization to happen. Remove the entries for the old PDC out of WINS and Server Manager.
Now, reboot the old PDC (it should show as BDC or cause a election for PDC) whichever happens, once normalized, apply the SP and reboot. Syncronize the network once again, allow time for update, then if the old PDC still is a BDC, promote it to PDC and do another syncronization.
I hope this long steps are making sense to you.

Good luck!

We don't have a BDC. The only machine in the Server Manager that is active is the PDC.

This can happen if there is a TCP/IP problem. If the PDC is also a WINS server, make sure both WINS Server settings point back at itself. Make sure the IP address is still the one you want and check the link lights for activity. I had one server lose the PCI Network Card and had to reinstall it, then reboot.
Hope this helps.

I did find one of the solutions in technet to suggest a binding problem. This didn't work either.

Thanks

I would check the event log, look for Red dots in the system log at 11:03. Also try simple tests like Ping. Look in the Control Panel, Services, and stop and start the netlogon service.

The red dots in the system log of the event log are pointing to a problematic serial port and they've been like that for a year.

The only thing that seems to be related to this is a TCP/IP WINS client binding on the WAN Wrapper 1 and 2

Plug the RJ-45 cable into the back of the PC :)

Failing that why did you reboot the PC?
Did you make changes to the Network settings?
What did you change?
Work backwards and you will find your answer.

As a last resort remove your protocolsand the reinstall them. AS it is the PDC ensure that IP address and subnet is correct.

Once you have reached the stage where you can ping other computers on the network simply check your DHCP server settings and you're away.

Cheers,

Dirk

Happy Fingers at the office in my abscense thought that the server was too slow and they rebooted. But prior to this, the Web developers were apparently working on the server.
