I use MS Office2000 professional and MS Back Office and am having trouble on a small, 5 computer network, sharing things like my calendar and contacts. Every so often, when I reboot, and go to File, then Share, Sharing is greyed out and therefore unavailable. The only fix I have happened upon is to use "detect and repair" and insert the Office2000 disk and wait about 10 minutes while it does whatever it does. When I reboot, it's fixed. This is getting tiring. Any ideas?
