After previous team members STIG'd the Exchange environment here odd things started occuring that we can't seem to nail down the root cause of...
1. Management Tool Console (only functions on 1 server all other attempts have this error):
"The attempt to connect to http://SERVER.DOMAIN/PowerShell
using "Kerberos" autehtncation failed: Connecting to the remote server failed with the following error message: The WinRM Client cannot complete the operation within the time specified. Check is the machine name is valid and is reachabvle over the network and firewall exception for Windows Remote Management Service is enabled."
I've created a specific Firewall rule to troubleshoot this, tied it to the service winrm and allowed all connections both in coming and out going for both the main server and the server attempting to connect to it.
2. Autodiscover will NOT stay functioning... seems like as soon as I get it to work it breaks a few days later. There was no "Require SSL" set on the Autodiscover VD and once I set that and restarted IIS I was able to test OK, three days later it stops working for some reason and there have been no changes with Internal URL, DNS, etc and no event logs. Just pops up a server unavailable error and then crashes outlook on second attempt to launch out of office. The original testing of Autodiscover seemed like it wasn't able to resolve any URLs on the client side, once I put on SSL require for that Virtual Directory it would immediately and for a few days then it stopped working again .
I've looked at a lot of webpages out there and haven't found any that resolve my issue. Google doesn't even pull up any I haven't seen yet.
I will be doing the following tool but am awaiting approval and also am doubtful that it will help since MS's whitepaper on the exchange management connection issues don't apply at all to the error above.
I have downloaded and used http://gallery.technet.microsoft.com/office/Exchange-2010-Architecture-9368ff56/view/Discussions
and while it is a great tool it hasn't helped me.
Any help would be greatly appreciated!
