Did I get wrong on the back up process in server 2000?

Hi! I am having problems with my server. I was using Server 2000 DC but then the hard drive failed so, I got myself a new hard drive.

I installed in it Server 2000 and copied into it all of my files from my backup. The thing is while I was able to back up everything, none of the client machines would connect to the server and I could not view My Documents. Aside from that, I have also encountered other problems.

For one, I get this error message saying “dcgetdcname call failed”.

I also could not open the group policy and the computer sends me another error message saying “Failed to find a domain controller.

There may be a policy that prevents you from selecting another domain controller.” There are also times when the Active Directory would not open; A Time Server could not be located; the server holding the PDC is down; and the NIC would not save static IP settings even if the machine IP does not change.I used to have three DC servers but I only have one now since I had troubles due to hardware failures.

This one I am using right now carries out all FMSO tasks. I hope somebody could help me.

I have too many errors in my hands. Thank you.
