Hi,

Here are some suggestions:

Check if the new Exchange 2019 Server can access the domain controller in the DR site.
Make sure IPv6 is enabled on the Exchange 2019 Server.
Check if the Microsoft Exchange Active Directory Topology Service on the Exchange 2019 Server is stopped during installation. If so, start it manually and see if the problem persists.

If suggestions above didn't help you with your problem,
please check the Application Log in the Event Viewer and see if it generates some warnings or error messages during a failed installtion.

Hi

Check if the Net.tcp port sharing service is started?

Answer

Had the same problem installing Exchange 2019, none of the existing suggestions on the web helped me, so I think I will share my solution on this problem.

We have an old AD with one site (Default-First-Site-Name).

In "AD Sites and Services" under "Sites|Default-First-Site-Name|Servers" there were several decommissioned DC's registered.

After removing these old DC*s from the list, the installation succeeded.

Exchange Topology Service uses this list, to determine DC's for the relevant site.

To others who may come across this, when searching for solutions.

Here the issue was the Microsoft Baseline GPO for domain controllers, where the user rights assignements "Debug programs" and "Manage auditing and security log" were overwritten.

Debug programs must contain:

BUILTIN\Administrators
Exchange Servers
Exchange Trusted Subsystem

Manage auditing and security log must contain:

BUILTIN\Administrators

Exchange Servers

The Exchange groups were missing and that caused the issue.To others who may come across this, when searching for solutions.
