Hello, I'm running a test lab for exchange servers and we have a need to force specific users to use CBA-enabled client access server. In our test setup we have two exchange 2007 server with Mailbox and client access roles installed to both servers. Lets call them server1 and server2. Server1 have client access without CBA and server2 have client access with CBA. We need to force Server1 mailbox-users to autodiscover only server1 information and server2 mailbox-users to autodiscover only server2 information. Currently I get server1 and server2 information randomly and it doesn't depend which server user i'm using. - Kimmo

Hi, What is the advantage of doing this? Generally you should put both the CAS on NLB and then give NLB URL as autodiscover URL. Also, sorry but what you mean by CBA? -V-V

HI, You are correct if this was a production environment. This is test lab which is used for testing a client for exchange server and we need to test client with CBA (Certificate Based Authentication) and without CBA. I think I need to create own domain just for Certificate based authentication and not mixing different CAS authentication settings inside the same Domain. - Kimmo
