I've been going through multiple threads and articles and figured I should post mine in case someone has an idea of what is wrong. I had hardware issues with my single CAS/HUB server and decided to replace it entirely. I brought up a new server, launches
services on it and downed the old server with the intention of replacing it. After installing the services on the new server and importing the SSL cert, I uninstalled Exchange from the old server and verified it was no longer listed using ADSI Edit in any
locations. As soon as I decommissionsed the server I started getting popups regarding windows security error (it was a prompt but no way to enter credentials).
Then I created a new VM as a secondary CAS/HUB server and used the same hostname / ip address (in case something was targetting it and causing the issue.
Now the firewall is configured to send exchange ports to CAS01 (.13) and these ports include 80/443 and SMTP/POP ports. These were already in the firewall and I simply pointed them to the new servers internal IP. (Sonicwall)
Then I used Digicert to rekey a new SSL license so that it also includs the new internal server (cas02.internal.local).
However if I run any AutoDiscover tests it fails. This wouldnt be a big deal if Outlook would launch correctly. If you launch Outlook when manually entering the data in the config of it - it will receive e-mail and show connected to exchange but then prompt you for credentials. But this prompt is a grey box saing Windows Security - displaying your email and then your only option is to cancel.
My auto discovery in outlook displays the following - after I uncheck the guesssmart options >
SMTP=myemail@company.com
Attempting URL https://cas01.domain.local/Autodiscover/Autodiscover.xml found through SCP
Autodiscover to https://CAS01.domain.local/Autodiscover/Autodiscover.xml starting
Getlasterror=12044; httpStatus=0
Autodiscover to https://HYCAS01.domain.local/Autodiscover/Autodiscover.xml Failed (0x80040113)
it continues to do this for the other server, and other hostnames (internet ones instead of local ones) and for Srv Record lookup.
Anyone have any idea how to figure this out?
