Hi,

  The remote desktop on this particular computer fails to connect to the terminal server "A" But ,at the same time, I can connect to other terminal servers "B" or "C"  from this computer.  However, when I connect to Terminal Severs (B or C) and from there, I can connect to Terminal Server "A" using remote desktop.
  Is there a fix to this problem?

Thanks.

Seems like you are having a connection issue.

Can you ping the TSA server from the station you are trying to connect from but failed

yes I can ping the ip address of the terminal server.

I stand corrected. I can't ping the ip address of the terminal server A from this computer. Before I posted this question, I was able to ping the IP, but now I can't even ping.
Now if I can't ping it, of course, I can't connect to it.
This is a remote area and the user has been using Spring 3G connection which I found out today is very slow. I looked around and found a switch inside the building.
So I connected ehternet cable to the switch and it delivers T1 speed.
I can surf the internet and connect to all the terminal servers of my customers from this computer, but i can't even ping ONE TERMINAL SERVER that I need to connect to even  thought I can connect to that terminal server thru another terminal server connection.

You can ping the IP address from the workstation you can't connect from. Are you using the same username across all TS servers? What is the actual error?

That is a network issue not TS issue

I agree. For some reason, this T1 line is blocking access to the IP address of the terminal server.
It is possible that on the TS in question RDP setup is strict, TS B and C meet the requirements but your computer does not.  Try updating your version of MSTSC. Here is a link for V 7 on XP

Windows 7 comes with this version.

In fact, I thought about that possibility.
My next step is to try connecting to TS on that laptop (Windows 7 Home OS) from a different location ( like when the users goes home) to see if the T1 environment was the problem or, like you said, it was requirement problem. I will keep you posted.

if you can't ping the server this point to a network connection issue from the location you are pinging from

"My next step is to try connecting to TS on that laptop (Windows 7 Home OS) from a different location ( like when the users goes home) to see if the T1 environment was the problem" ---> it worked from the user's home. So definitely there is something about her work network.
Any suggestions?

Network can be tons of things you need to start troubleshooting that part which really has nothing to do with the TS part

Why a grade of a C? The solution was a network issue. The original question was answered. If you wanted to troubleshoot the network issue which isn't the same as a TS issue a question should be opened for that issue. Hard for us to troubleshoot network issues without the information about your network.
