Dennis & Emmitt, Thanks for the replies and tweaking advice. Dennis's comment regarding, >>> "One thing that slows terminal server type situations from working is any part of the app which writes to the C: drive. When such an app is run on TS or Citrix, all the C drive writes have to go down the wire. This includes temp file access. I make sure to set up the server so that TEMP and TMP point to a separate directory local to the server." >>>
I assumed that the only thing going "down the wire" was writes to the screen, keyboard output, and printing, because even writes to "C" would be done at the server side. Not so?
