New Dell Workstation with XP - RDP 7.0 installed, how do I remove?

Long story, but I have two new Dell workstations running XP that have RDP 7 installed.  I am using mstsc to connect to a 2003 server.  In the software I am running on the server, there is a certain scheduling screen that refreshes very slowly on the Dells.  The only difference between these computers and the others that I can find is that they run RDP 7 (the two Dells are on different parts of the network).  All network connections are gigabit to procurve switches on each floor.  Switches are linked together with fiber, and all wiring tests for gigabit.  All that to say that it is not a network infrastructure issue.

It is not an account issue either - tried the same account from other computers (both older and newer, all running XP), and the refresh issue isn't there - only on the Dells.

My strategy at this point is to try and remove RDP 7 to test my theory, but Hotfix KB969084 doesn't show up in Add/Remove Programs and there is no C:\WINDOWS\$NtUninstallKB969084 to be found.  Was this update rolled into another later update?

Any idea how to get rid of RDP 7, or other thoughts?

Thanks!
