Has anyone experianced this? We run E2k SP3 & Outlook '02 with all SP's. Here we have about 1000 users at around 400 workstations. Of these, maybe 1 per week lose the ability to connect to connect to the Exchange server. Nothing we've tried brings it back. Removing from the domain, reinstalling Office, redo-ing SP's, nothing. The only "fix" is to rebuild the PC. We can ping the server and all that. There are no listings in any event logs. We are at a loss as to what in heck could be happening. I beg you all, if you've come accross this and figured it out, please share what you did! Each station runs the newest Mcaffee, the Servers run GFI Security & GFI Essentials.
