High CPU load on Domain Controller
Posted on 2007-10-09
We are experiencing high sustained CPU load on three of our domain controllers. Here is the basic functions of the domain controllers. They are all 2003 Server, 1 GB RAM, 3.2GHz Xeon processor.
They all are running DNS, printer queues for network printers and IAS for wireless RADIUS authentication.
Under the task manager, the processes that are showing ANY CPU usage are System and System Idle process.
We have rebooted and it solves the problem for a day and then the CPU starts to climb. It will go to 20% sustained, then 50%, then by the end of the week it will be above 75% and sometimes at 90% sustained. Any ideas on where to look?
