Seems recently I have had a rash of clients starting to get a login/password/domain prompt upon logining into Outlook/Exchange everytime they try to read their mail. Don't know why.. Here is what I have done.
OS: XP Professional SP 2
Application: Office XP / Outlook XP SP 2
Exchange : 2000 SP 3
1: Checked to ensure XP firewall is disabled.
2: Reinstalled Outlook and redone the Outlook profile.
3: We are not running any type of encryption methods.. Standard TCP/IP from the client to the server.
This is only happening on my machines that have XP Professional. My 2K with Outlook XP are running with no errors..
