Hello all - In general, I am getting issues with the Autodiscover service. I have read literally hundreds of pages of documentation and can not figure out where my config is incorrect. In my lab I have CAS/HUB installed on one server and MB on another. The CAS/HUB is configured as a CASArray (named CorpMail.gklabs.net). The CAS array only has one member at this time and the member is named NC10LABS050. I am using a UCC cert with the primary name being OWA.GKLabs.net. The SAN's are legacyOWA.gklabs.net, autodiscover.gklabs.net, www.owa.gklabs.net and corpmail.gklabs.net. OWA 2010 works fine for 2010 MB's and also 2003 MB's (redirection to legacyOWA). I am providing my general questions from Tests that I have ran along with their results to hopefully get some help from you. Sorry for the length but wanted to provide as much detail as some of you may need! 1. When I run a "Test-OutlookWebServices" test I get an SSL mismatch error. Why is the server looking for an SSL for the CAS server name https://nc10labs050.corp.gklabs.net/autodiscover/autodiscover.xml NC10LABS050? I have ran the "Set-ClientAccessServer -identity "NC10S050 -AutoDiscoverServiceInternalUri https://owa.gklabs.net/autodiscover/autodiscover.xml" and I was under the impression this is the address internal users should be resolving to. How can I change this to match the Primary name on the UCC Cert? 2. Also from the 'Get-AutodiscoverVirtualDirectory |fl" the internal and external URL's are blank. I have read that these are surpressed for security reasons so I assume this is correct if they are blank and the AutoDiscoverServiceInternalUri has been set. 3. When running testexchangeconnectivity.com tests with a 2010 MB user, I am getting HTTP 401 denied results. 4. When visiting https://owa.gklabs.net/autodiscover/autodiscover.xml I am prompted for credentials. Regardless of what credentials I provide (admin or regular MB user) it always errors out with 401.1 unauthorized. I have verified permissions on the Autodiscover directory has Anonymous, Basic and Windows authentication - SSL required, with 'ignore' selected. Authenticated Users also have Read & Execute permissions on the directory for Autodiscover.

Thanks for the reply Ed - 1. After reading your response, I went back and re-read my post b/c I thought I had provided all results. I had mistyped the name of the test I ran in question #1 so it appeared I left out some info. I have corrected the original post so it makes more sense and clears up any confusion. Thanks for the heads up. 2. I will run at Set-AutodiscoverVirtualDirectory to set the blank internal and external Url's. I will reply with the results.

Thanks to everyone that responded to this message. Even though this is a lab environment, I placed a call to Microsoft PSS. After spending two days with Exchange support, we couldnt find an issue with the Exchange config and seemed to be something else with authentication causing the service to fail. They eventually tried to resolve using http://support.microsoft.com/kb/216393 however this didnt work, so we had to manually disjoin and then rejoin the Server to the domain - see below. Seems that the CAS server (NC10LABS050) had been generating 3210 Netlogon errors. Long story short, the computer account and/or local security accounts were corrupt.... To fix this issue, I simply stopped and disabled ALL exchange services. Rebooted. Removed the computer from the domain. Rebooted. Added the computer back to the domain. Rebooted. Set the exchange services back to their normal Automatic, Manual, etc. status and rebooted one final time. Once the server came back on line, credentials were able to be passed and all exchange autodiscover services worked perfectly. Thanks to everyone on this list who responded and offered assistance. It was much appreciated! Wall
