Hi, first time posting so bear with me.
We have built a root forest with 2 tree domains off it all on Server 2019. Exchange 2019 installed on tree domain1.local and works fine, i can see the certificates in the ECP console and on EMS powershell. On tree domain2.local, we installed exchange 2019 and installs fine. The ECP console can see both servers and we can create users on either exchange server etc.
The issue is the certificates. if i go to the certificate tab on ECP and select domain2.local from the drop down box, i get an error "Cannot connect to the remote procedure call service on the server named DOMAIN2. Verify that a valid computer name was used and the Microsoft Exchange Service Host service is started." If i select DOMAIN1, certificates are there and showing. On EMS powershell, i can see the certificates on both exchange servers.
DOMAIN2:
PS] C:\Windows\system32>Get-ExchangeCertificate -server DOMAIN2

Both Exchanges live on thier own servers in their respective domains and they are not domain controllers. Replication between domains is working fine without errors. All servers at same level and patch wise
Is there anything I am missing here? This may be normal but i cant find anything googleing that represents the same problem i have with the same setup. Any help would be greatly appreciated.
Regards
Tyron
