Is there any quicker way outside of a SS restoral to re-add computers back to the domain without having to touch each machine and completing the process to rejoin?
Maybe a reliable VB or PowerShell script run remotely perhaps?

You could use netdom with psexec, the problem is whether you have a local admin logon active that you can use.
Rejoining systems is one of several steps. User account creation, OU, GPO, logon script, etc.

Restoring system state is needed only if there was a single DC, in a multi DC the rebuilt system should simply rejoin the AD and with dcpromo get promoted back to the DC role.

Found Powershell cmd "add-computer".  What is required to run this on a remote computer and can you call a script from within PowerShell?

BTW - Both DCs were affected, could not login with any account, think a virus.  Had a password recovery tool but could not find the RAID controller and I did not know how to incorporate the drivers with the boot USB drive.

You can use psexec from sysinternals

Create a powershell script joindomain.ps1
Psexec computername -s -c -u remoteloginusername 'joindomain.ps1'

You must use remote system's local admin.  Test first.
Not sure the ps1 is mapped.  Using netdom might be simpler or joining each system which you can login into using cached credentials while the DCs are inaccessible.
