Unkown Resource Drain

I have 3 machines that crash because of resource drain. I have spent few minutes and figured out that in the END Task window there is a program WINOLDAP. It is running in the backgroud and replicating. As long as the user goes to end task and closes30 – 40 instances of it every day, the machines run fine. If the winoldap is allowed to spawn system crashes.
Anybody heard of an issue like this?
I just took over from an old admin and those 3 machines are not a priority so i never have time to really check them out.
They are all K6 400 with 128 mb ram.
