Are you in a position to migrate to a different host? That would be quick and easy. In any case, check other Windows VMs on the same host and see if they are having similar problems.

It is a VMWare guest. It has been running at 95%+ memory utilization. I’m not sure for how long, but I happened to see an alarm for CPU utilization on the guest when I was in vCenter yesterday afternoon. When I RDP into the domain controller, it is very slow to login. I open Task Manager, and on the Performance tab, Memory is at 98%, and steady. I look at the Processes tab, and the memory shown as used doesn’t add up. There are lots of processes using memory, but the largest user is using around 100MB. The box has 4GB assigned. Looking at the Details tab doesn’t shed any more light on the issue. So, our first thought is some kind of memory leak, so we schedule and perform a reboot last night. As soon as the box comes back up, I log in, and memory is right back at 98%. I compare with a couple other DCs, and one of those has around the same number of processes running, but its highest user is right around 1GB, and its overall usage is around 60%. What other tools can I use to help figure out where that memory is going?
