http://www.msexchange.org -------------------------------------------------------See if this answers any questions on CAS placement.. maybe I’m misunderstanding, but it’s a good read anyway ☺. http://blogs.msdn.com/brad_hughes/default.aspx Thanks. Lee Swanson From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Praveen Ramaswamy Sent: Friday, March 20, 2009 7:44 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] sudden Authntication pop for outlook 2007 We have Exchange 2007 SP1 roll up6 (on windows 2008 sp1)CAS server in 4 sites. One site is separated by firewall and this site has the first CAS server installed in the ORG. Issue is, outlook 2007 users are suddenly getting authentication popup and this pop is from CAS server in different site. Not able to understand why it tries to connect to CAS in other site. We also observed that in outlook proxy setting, the msstd setting gets pointed to the first CAS server URL automatically. This auto discovery is creating hell. Above this out office assistance is not working when NOT connected to domain or not logged on to domain. So now people from internet and people logged on to different domain cannot put out office. Can someone throw some light on this. Not sure what’s wrong.
