Power Surge with Catastrophic results on W2k Domain

[Bigtm]

Hello, I recently visited a site with my Boss which has suffered a fire resulting in huge power spikes before power was completely gone. To make things worse the company was runing 6 w2k DC's without a UPS or surge protected sockets.

As a result 3 of the 6 DC's are completely knackered with the hard drives completely inaccesible. We enquired about backups but you can gues what they said.

The question is this. 3 of the remaining DC still work but within the AD schema they register the other 3 DC as Domain controllers. is there a way to force remove the downed servers from AD? Bear in mind that the downed servers are gone so it is not possible to transfer roles, perform migrations or demotions. They had 6, now down to 3 and they need to make the PDC think that now there are only 3 DC left

Does that make sence?

Many Thanks
BigTM.

You will need to use the NTDSUTIL command to;
1. Transfer the FSMO roles that were assigned to the failed DCs (if necessary)
2. Remove the failed DCs

Unfortunately I haven't done this in awhile so you will need to refer to the MS knowledge base regarding the proper syntax and method. Hope this helps
