If you're not on a native windows terminal, you can can access a Windows desktop through the citrix software installed on all department UNIX machines. Just run citrix from a command prompt.
The citrix client can be configured with wfcmgr to change window size, color depth, and sound options. It can easily be set to be full-screen, giving the illusion of sitting directly at a PC.
Note that you need a Windows account and password to be able to log into the citrix server. Visit Staffworld, AVW 4120, if you don't already have one.
