We have recently upgraded srv1 to exchange sp3 from Exchange sp1. This server was upgraded to try to eliminate the outlook asking for a password. Clients connected to srv1 still are getting this issue.
Clients are running Windows 7 + Outlook 2010
we have removed, KB2553248 which removed half of the issue, laptop users now no longer get prompted for smart card , but desktop users are still getting prompted for a password.
