Major screw-up here and I need to find out how much trouble I am in.

I have an AD machine that is running Server 2008 R2, hyperv, DHCP and DNS. On the hyperv machine, I have a backup AD instance running along with a handfull of other server 2008 instances.

One of the instances is running Acronis backup which has a current (last night) backup of the hyperv machine.

Sysprep was run on the hyperv machine instead of one of the instances.

What did I lose and what are the basic steps to get back the environment?

Restore from your last good backup? –  Zoredache Jan 31 '12 at 19:15
    
That should be an answer, zoredache :-) Actually, the answer... –  mfinni Jan 31 '12 at 19:17
    
I have a good backup using Acronis but I hate to go that route unless I have to. The Acronis software was running on one of the instances. –  rboarman Jan 31 '12 at 19:18

Why the down vote? At least leave a comment. –  rboarman Jan 31 '12 at 19:49

Are you saying the machine storing your backups is a virtual machine running on the machine it's backing up? When you get this all sorted out, you're going to fix that, right? –  fizban Feb 3 '12 at 19:33

If you have a good backup, then try doing a restore of the system state. Most of what sysprep does is related to that.

I have to figure out how to run the acronis guest instance, then I can boot from the Acronis CD and restore the machine. I am not sure of Acronis can restore just the system state but I will check. Thank you. –  rboarman Jan 31 '12 at 19:37

Is this for a work environment? Because you should be able to replace a smoked VM host without having to depend on what's in it. If the thing was just running AD/DNS/DHCP, then it would be easiest to migrate all of the guests off of it, and just do a plain new install followed by a DCPromo, and then rebuild your DHCP server, hopefully it wasn't too complicated.

Worst case you can pop the hdd into another host and copy them off manually. Importing them by hand is a pain though because you have to symlink all the XML config files by hand. –  Mark Henderson Jan 31 '12 at 20:29
