Autodiscover in Exchange 2010 Certification Warning

Postby guest » Fri Mar 30, 2012 9:53 pm

I´ve got an Autodiscover error that is being difficult to sort out.Here the scenario: I have Exchange 2010, Enterprise edition servers deployed on Windows 2008 R2 Enterprise. I got 2 CAS servers with only CAS role intalled on them in Windows NLB with CAS Array configuration. No Certificates installed. All Ports are open on NLB. NLB name is "nlbcas.smpn.net". Cas array name is "casarraysitea", FQDN is "casarraysitea.smpn.net" Site Name is "SiteA". CAS servers names are - SRPAPXCH03 and SRPAPXCH04. There are 2 Mailbox servers in a DAG configuration, installed in 2 separate servers with roles Mailbox, HUB and UM.

When I open Outlook 2010 I get this message: "The security certificate was issued by a company you have not chosen to trust. View the certificate to determine wether you want to trust the certifying authority". Then the user have to click on the "OK" button to proceed and then access his mailbox.

The name that was being shown was the NLB name: I changed that name to the CAS Array Name and the same error happend.Then I used the following commands do set the autodiscover to the individual CAS server names:

Set-ClientAccessServer -identity srpapxch03 -AutodiscoverServiceInternalUri "https://srpapxch03.smpn.net/Autodiscover/Autodiscover.xml"

Set-ClientAccessServer -identity srpapxch04 -AutodiscoverServiceInternalUri "https://srpapxch04.smpn.net/Autodiscover/Autodiscover.xml"

EWS and OAB were configured the same way, to their respective CAS server names. Am I missing an internal CA authority, or there is a powershell command that gets rid of this error?

I really need help with ths..
