Cannot remove DC from Network

Hey guys,

We have a DC in one of our Hyper-V VM environments that has a lot of problems.  It appears that system files have been corrupted.  I ran sfc /scannow and it didn't resolve the issue.  MMC snap-ins don't load and other stuff doesn't function properly.

So we went ahead and decided to create a new DC and moved all the FSMO roles to the new DC.  However when I try to remove the old DC using dcpromo /forceremoval I receive the error below.  I haven't really found any articles that were very helpful.  If anyone can shed some light on what's going on here I'd greatly appreciate it.  Thanks!
