Server busy "Retry" "Switch To"


We just built a terminal server 2008 R2 so users can log into it and access Dynamic GP.  The GP database is installed on another server.   When the user tries to upload a file to a record, the message would popup with "Server busy, Retry or switch to options". Switch to option brings back to the Windows Start menu.  I remember the "Retry" option doesn't do anything.

The user is able to log in and do the same function on a workstation (using another staff workstation).  We built the terminal server since she is using a MAC :(

I have done some readings in general but figure I post here first.
