The entire app and data was moved to one of the workstations local hard drives and the hardware tech tested running it locally on it and it was just as slow. 3-4 second delays. The same test on the one P4/512mb workstation was perfectly fine. No delay at all.

I don't know if it's been mentioned in any other message on this thread but has AV on the problem workstation(s) been disabled for testing, and/or have file exclusions been set for all the app's files?

I'm assuming you've done some basic checking in Task Manager to see how much RAM/CPU etc. is being used when you run the app locally on a WS. Is your app forcing the box to page to disk?

A 1.7GHz Celeron may be slow by the standards of new computers today but in terms of local disk and network I/O it shouldn't be a lot slower than a P4 box.
