Question : RDP Fails to Connect

When I try to Remote Desktop inside of our LAN to a particular desktop, it does not connect.  Produces no error.  Click on Connect, and it just leaves you at the RDP  prompt.  If I connect to other RDP hosts, no problem.  The problematic target host has TS running as well as any other services that starts with "Remote ...".  Plug a working RDP host into the same jack, no problem.  Firewall is not turned on.  I can not see a difference between it and any other PC, except that it is a Dell.  It is running from the same corporate install of XP Prof as other models in our environment though.  I can RDP FROM this problem host to another workstation without any problem, although I don't think that lends to helping with this situation.

Any clue as to what else can be causing this?

Answer : RDP Fails to Connect

The link to my last post leads to the solution. It was the video driver with that make / model of Optiplex 755.  The PRO is what is needed, even though it by default came from Dell using the other driver.
