I ran window updates on all our Servers, However when restoring our servers last weekend on the test environment I noticed that 3 of the 4 vms loaded fine, However our DC (Also which stores our sage files) failed to load up the windows error upon start up was 0xc00002e2.... Also with the blue screen of death (Googling this Error is AD related) None of the other DC have been affected)
The only way the vm works if I go into Directory services restore mode.....
However the Live vm has been working fine and showing no errors.
I have created new jobs and restored them with the same issue. However when I involve any job which Changes the UUID and resets the VM state this will restore.
I have run integrity checks on the test environment and it doesnt throw up any errors there is nothing in the logs. Really confused as to what it would be

Does anyone have any ideas?
