Why am I getting a "Time Out" or "Session Expired" error?

You may get a Time Out or Session Expired message for a few reasons:
Some firewall products, for example Zone Alarm, will cause this message to appear. Try changing the security level (for example: from high to medium) or try temporarily disabling your firewall. After making any changes, remember to close out of your browser, reopen it and then try logging in again. If you are using Internet Explorer, be sure that you are going out to the Microsoft site for the Windows critical updates and installing them.
