Terminal Service Manager in Windows 2008 Standard 64bit Server

I have Terminal server running on windows 2008 Standard 64bit server.
its all activated and works fine.
the only problem I am having is using Terminal Service Manager.
I have created agroup under my domain server and I can access and send message to server but everytime I tried to add computer the follwoing two error messages comes.
First Error Message
"The specified computer cannot be reached. Make sure that the computer is accessible and varify computer name"

Second Error Message
"The RPC server is unavailable"

I can access the PC's remotely. I have enables remote access, but I cannot connect or add any of the computers to the group. I keep getting above messages on some I get error 1 and on some I get error2.

the reason I want to use this service is because so that I can send messages to all 20 users at a time.

can you please help

Check the windows firewall, unlike Windows2003 server, windows2008 server automatically enables the windows firewall service, and even though you have selected to enable Terminal Server this is not then authorised in the firewall. You can either tick the RDP protocol in the firewall to enable it, or just switch windows firewall off. This is probably why you can't connect to the RDP service.
Hope this helps
