While running any part of the flow in Windows NT (NGDBUILD, Map, PAR, Timing, BitGen) one of the following two error messages may appear :
"RPC unavailable" or "The object invoked has been diconnected from it's client".
The implementation window then stays up until you close it. Clicking on the stop button brings up the dialog window to confirm abort, but doesn't seem to have any effect.
This error will only occur in the GUI. Running the tools via the command line will not return this error.

The machine may not have TCP/IP installed.
- Go to Start-->Settings-->Control Panel and select the Network icon.
- Install the TCP/IP protocol from the NT installation disk. This must be installed even if the machine will not be accessing a network.
