Microsoft Office 2003 applications crash on 'Save As' to a network mapped drive

"Check any other drives you might have mapped in Windows. They might be mapped with expired credentials or the connection might not be working. If there are other mapped drives, try disconnecting them, if possible, to see if it comes up any faster.

I remember in XP having the ""Retrieving list of folders..."" message come up CONSTANTLY and it drove me nuts til I found out I had a drive mapped and hadn't remapped it since I changed a password."
