Windows NT 4 Server PDC Crash

Hi Experts,

This is bad, disaster struck today, i rebooted my NT4 PDC server today and got the dreaded blue screen of death, it turned out that one of the updates from windows update replaced a multi processor ntoskrnl file with a single processor file. With this the server would not boot, so i contacted microsoft who pointed me in the direction of a fix, after several hours trying to get this fix to work i gave up, all the users on the network were crying looking to use there pcs. So i no option but to install a completely fresh version of NT4 Server and configure it as a PDC in the hope that i could restore the winnt folder i have on a tape.

I use arcserver to backup my c drive and i have a copy of the orginal c:\drive on the tape, thing is am i going down the right track here, becasue i really dont want to have to reenter all my users accounts again and reset up all the permissions on the network shares.

I have a BDC on site but when i goto Server Manager on it to see if i can promote it says cannot find domain.

What am i to do, should i just start keying in all the users accounts again or is there a directory on the tape that i can restore which will save me having to do this, also i dont want to restore the whole tape because i think it will restore the orginal windows update as well therefore crashing the server all over again.

Really sorry bout this long one.

You can restore the system and sam file usually in winnt\system32\config folder...
In fact. just restore the entire registry.  THen you can restore files later and it should all work..

But the system accoutns are stored in the Registry... which SAM is a file that has all the accounts in it.

I know, brief and sloppy.. but I hope it helps.

but when i goto copy over the system32 config folder its gives me access denied
restore it offline then, you can either take out the HD, or boot to alternate environment.
