Exchange AD Topology fails to start/Unable to deploy New Exchange Servers**
I have several on premise Exchange Servers 2019 on my domain. Within the past few weeks all of my servers have stopped working. I have verified that the VM’s have sufficient resources. Also any attempts to deploy additional exchange server makes it through the \exchprep, but fails out during the .\exchangeInstall.
One of the biggest issues. I have identified is that the Exchange AD Topology fails to start.
Any recommendations regarding how to get the EXCHANGE AD Topology to start and how to successfully install New Exchange Servers would appreciated.

Hi Struggle Bus Champ ，
For Exchange AD topology services that fail to start, it is recommended that you could review the related error events that are included in Event Viewer. This may provide the cause of the failure.
And maybe you can share the screenshot of errors after removing all privacy information like domain name and email addresses. This will let us to better research your issue.
