I am testing my new application on IIS 5.1 and I am experiencing slowness. If i do the test with both the client application and the web service on my machine I achieve 600 messages per second. This, however, maxes out my CPU and is not an accurate test of the Web Service, so I moved the client app on...

I have the same problem. I note that when crash occurs, an executable DW20.exe is running 25% of CPU for 3-4 minutes. No special error in httperr logs. I do not find any user.dmp on the server. Where this file may be saved ?
