I am currently working on a project to figure out why out of the blue. MS Office 2003 hangs while in use. Everything is slow, Excel specifically as clients edit cells it will take up to 15 seconds to jump to the next cell. Opening attachments from Outlook, cache mode is enabled. The server is in the building running server 2000. We have the Files, Printers, and Exchange server here. Printers also have been an issue, however not as important as getting Office running properly. Any ideas?
