I have some users set up in a work group. They can all open Outlook 2000 without authenticating to Exchange 2000 server with username, domain and password except for 2 users. I went through all the settings in outlook and active directory and compared with a user that works. I can't see anything different. I was able to resolve this issue with the users on the network by going into user accounts in the control panel on their desktop. No luck at all for ones in the work group. Any advice will be greatly appreciated. Thanks
