Terminal Service connection to Workstation fails

[lanrat]

Hi,
This is a regular SBS 2003 Server based domain with < 20 workstations.
From the "Server Management_Client Computers" interface on the SBS 2003 box I rht-clk on any workstation and select "Connect using Terminal Services" to logon to any of the workstations on a regular basis.

Recently however ONE (and only one) of the workstations returns the error "This computer can't connect to the remote computer.
The connection was lost due to a network error. Try connecting again. ....."

I can ping both the name and IP of the workstation.
I can connect to the machine using LogMeIn from inside and outside the domain.
I CANNOT use RWW to connect (to THIS workstation)
I CANNOT use RDP to connect (to THIS workstation)

I have updated the NIC drivers on this workstation.

Hope someone can point me in the right direction with this -
Thanks,

Firewall settings on workstation? AV firewall?
