ProSoft NetWare? Tread very , very carefully. This application, which I use to (attempt) to connect to my work's Novell network, is majorly buggy. When it works it works pretty well. But it is written on some of the most fragile code I have ever experienced. It just up and quits, or at least says it does, at least five times a day for me. More fatal, however, are the kernel panics it causes on my MBP. My laptop is absolutely rock solid until I boot NetWare, and then the prayers begin. If you do use NetWare you absolutely, absolutely, abolutely must log off the network and quit the application before you shut down your machine. Otherwise, BAM! kernel panic!
If you can, convince your IT people to allow you to connect to your network servers using AFP or SMB. Then you can just connect to the network drives from the Go>connect to server function in OS X. I do this to other servers and it works flawlessly. Your IT people might already have it enabled. If you can get the IP address for the server you are trying to access at your job you can give it a try. Then your experiment will be a success. I wish you luck (my IT people won't cooperate on the AFP or SMB front at all).
