I cannot install exchange 2019 on server 2019
Firewall does not appear to be an issue according to the network engineer. All ports are open. Also a newly static IP address does not solve the issue.

kinda hard to answer with no information.
What are the errors exactly? Where does it fail?
Hi @JustinMicheal-7973 ,
Have you run the preparation tasks? See this topic: https://docs.microsoft.com/en-us/exchange/plan-and-deploy/prerequisites?view=exchserver-2019#exchange-2019-mailbox-servers-on-windows-server-2019
That means you should install these softwares before installing the Exchange server.
And also if you gonna install Exchange with unattendant mode, you should first make your AD environment prepared.

I’ve got good new. I’ve got both servers running after I had the policy changed enabling the Computer Configuration -> Windows Settings -> Security Settings -> Local Policies/Security Options
Network Security: Configure encryption types allowed for Kerberos RC4_HMAC_MD5 cypher in the policy.
This solved all our problems.
I have only one question left; can you explain this behaviour?

Hi @JustinMicheal-7973 ,
Glad to know your issue is resolved now.
Well it's hard to say, I don't know much about the cyphers, but for sure the Exchange server uses Kerberos for the authentication with AD.
Seems like the Kerberos is the default or a preferred choice:

Yes I would like to know if this should be enabled by default or not.
