Please help

The computers at the lab at my university are running Novell.

I tried to implement a suggestion I received on this newsgrup and use
PSEXEC program to remotely log into another machine on the network. The
program requires me to type a command like this:
psexec \\IB2004_21, IB2004_18 -u user, -p password

where "IB2004_21" is the name of my machine and IB2004_18" is the
machine I want to log into remotely. I get an error message
"network path not found".

How can I find out the network path of my machine?

Thank you for your kind help!
