because I just have found this forum.<BR>We have an application using the middle-tier component running on the NT4 server machine. My company just switched from NT 4.0 to Win2000 on the user&#039;s desktop. The application started running very slow after that. <BR>I tried to run the Performance Manager looking at %Processor time counter, some memory and disk counters. It seems that the server is just fine.<BR>Is there a way to check how the middle-tier component is running (timing, etc)? Maybe some third-party tools?<BR>Appreciate.<BR>Lana
