USE Com1: "\\Client\Com1:"

I am now recieving the error 'the device is invalid' I am assumming com1 is invalid. Once I am fully log into the net work I am able to map the above command manually. Any clues as to this error would be appreciated. This script is running on an NT4 Terminal Server, with the lastest SP's.

Welcome to the board.

Some question?
- was the script always running on an NT4 terminal server, or did you migrate
to it?
- what kixtart version you are running?
- what is the effect when you use the net use instead of use command?
f.e. "net use" by your batch file or by a SHELL kixtart function call.
greetings.
