Try to run a repair form the DVD and see if you can fix it. If not, you will have to reload the DC and do an authorative restore - or you'll be digging metadata out of AD.

don't do authorative restore as their is no roles and nothing to worry about...
just do the metadata cleanup.
install the server with different name to be on safer side and promote the server ..

Sorry - I didn't see where it said the FSMO roles are already migrated off.

Anybody have experience with repairing from dvd? Is it ever succesfull?
Just don't want to loose time trying this if it appears success rates are low and need to reinstall after all.

it will be better to reinstall... if the server has crashed... just a small process of Metadata cleanup is requierd.

this is what normally is done incase DC crashes and which do not have FSMO roles.

Ok, but I rally still would like the same DNS name for it. I know, to  avoid any risk, it's better to use a new name. But it makes things more complicated if I use another name (organistational wise).

I found this and am trying it right now (might come in handy when I really need to recover):

Boot from OS install disk

Select next after making sure the language options are correct.
Select Repair option
Select CMD
CD into recovery
Type Dir
Run the last command in the list. (don't remember the name off of the top of my head)

That should do a basic repair to the OS.

if you want to use same name make sure after meta data cleanup  to delete entries in DNS also.

give time for the replication to complete.

You can try the the OS repair as specified in the link.

That should not be an issue if the metadata is gone, you should be fine.

Root cause was sync of vm to time of esx, althought vmware tools doesn't have the option enabled to sync with ESX.
