I have a Win2K Adv terminal server running in the applications mode. It is a 1.4G AMD machine with 1 gig of ram. The WAN connection is via ADSL with about 5 users accessing through the WAN with MS's TSAC. These users run 1 program, a customized 32 bit billing program written in Clarion. The program files reside on another file server and are accessed through a normal share. The problem comes from CPU going to 100% which makes the TS appear to freeze. It does not seem to be any particular user and I cannot detect any pattern to the problem. Of course the software vendor has "never seen this problem before". When I look at the task manager I can see the process hoging the cpu and can kill the process. I would really like to fix this as it is making an old man out of me.
