DNS working but unable to snapin

Ok, I found an employee attempting to enable Windows Deployment Services on my domain controller. I stopped it and had the process cancelled and ever since then I am running into issues with this Domain Controller.

The funny thisng is this. DNS is working on the DC. I can open DNS via my workstations Admin Tools but when you are on the DC and click DNS in Admin Tools it will not load the snapin. I have attempted to run MMC and snap it in manually but DNS is not an option. So far I have

1. Restarted the DC
2. Restarted the DNS Server service

Event Viewer shows DNS successfully performing zone transfers. So I am at a loss for what this is. I have read many topics but in each instance DNS wasn't working or it was someone did not know how to right click and add server, I do not get these options. DNSMGMT.MSC is in the system32 folder.

I had two event errors this morning but they cleared with a restart
