This is very vague.

Are you using a Microsoft Active Directory? If so, have you logged into the AD to see if the user accounts are still there?

Also... when you attempt to use a domain username to log into something, what error do you get? If it's saying the account is locked, you may have a virus on your AD server.

We are using AD server 2003 and I have a backup of the system state. Will this restore my users and system accounts?

Thanks for this.  I wound up calling microsoft.  I restored the system state from a backup after I booted into recovery safe mode.  We ran NTDSUTIL  I demoted my 2nd dc down to a server right after I lost the user accounts so there was only one DC to restore.  We did the following:

2. Authoritative (Rare): Restoring "Authoritatively" will require the use of the Microsoft utility, "Ntdsutil.exe." Visit the Microsoft Knowledge Base for details on how to run Ntdsutil.exe. This option should only be used when all DCs need to be restored back to a certain time. The Ntdsutil is needed to change the type of restore to Authoritative. In general, the Ntdsutil will add a value (10,000 is default) to all USNs to ensure they will be higher than any other current DCs. Once the restore is done and the Ntdsutil utility is run, replication will occur and the entire active directory will be pushed to the other DCs upon reboot. This effectively overwrites any changes made from the time of backup to the current time. An example of this can be seen in TechNote 236363.

I'm happy to say that I got it all back with the Help Of Microsoft Tech Support - it was well worth the $260.00l
