When you contact the help desk, they will ask for certain information. It is usually difficult to diagnose and fix the problem without this information, so the more you can provide initially, the better.
What are you trying to do?
What happens?
What screen were you looking at, and what did you click on when the error happened?
If you received an error message, what was it?
What computer did the error occur on? Was it at home? In your office?
What browser (Internet Explorer, Netscape, Mozilla, etc) are you using?
How can we reach you, both e-mail and phone. (And if you are using a dial-up internet connection, how can we reach you while you are on-line?)
