I have two exchange servers in my domain which are in a DAG. Now I want to install another exchange But I got error which says that can not start MSExchange Service Host (it stuck in starting while the type is a automatic). In this case I neither can Uninstall the exchange in third server because it says I have uncompleted install nor I can finish the installation because of this error. I do all prerequist which are necessary for installation and also al exchanges in domain are exchange 2019 CU13. I am posting a picture of the error I get during the installation :
Error:

Hi @ Hadi Ramezani,
Based on your description, we know that this service has set the startup type to Automatic and still fails.
Therefore, I recommend that you manually restart this service and see if it installs successfully. The specific steps are as follows:
Restart the server.
Run Exchange Server Setup.exe .
When you perform the steps that require restarting the MSExchangeServiceHost service, manually restart the service through service.msc.
If you cannot manually start the MSExchangeServiceHost service, please check the application log in the event viewer to see if there are any error.
Maybe you can share the screenshot after removing all privacy information like domain name and email addresses.
Thank you for your understanding!

Hi Dear @ Aholic Liang
I checked the entire events related to the Exchange installation and I got the following errors. In addition, I also sent the error that causes the installation to stop. Meanwhile, the Microsoft Exchange Service Host remains starting State and practically grays out and I cannot stop or start it.
Hi,
Thank you for the relevant information.
According to the error of Event ID 4027 and Event ID 2142, it is usually due to network reasons that the current server and DC cannot connect.
Check if there are any firewalls or gateways in your current environment that are blocking certain ports.
If it exists, close it and try again.

I have seen this issue while installing Exchange Server 2019 before, and I solved this by using the below steps.
