KB4469600 - FIX: Peer-to-peer replication fails in SQL Server 2016 and 2017 if the host name is not uppercase


Assume that you have Microsoft SQL Server 2016 or 2017 installed on an Azure virtual machine (VM) whose name is not spelled as all uppercase letters. After you restart the SQL Server service, you notice that peer-to-peer replication fails. Additionally, you may receive an error message that resembles the following:

No peers were found for Production. If you encounter this error when executing the stored procedure sp_requestpeerresponse, verify that subscriptions have been created before attempting to call the procedure again. If you encounter this error in other circumstances, contact Customer Support Services. (Source: MSSQLServer, Error number: 20807)
