I have rebuilt my AD domain and since this morning about 1 in 5 times = when I go into AD Users and Computers on the server it doesn't open it = up but mmc.exe takes up 99% of the CPU. If I have the task manager open I can kill it via this, and everything = is fine again until I try again. Has anyone come across this before?
