Replication error - "The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))" (4380267)

After transitioning both primary and secondary RMAD servers from old OS/VM to new OS/VM, the primary had all the computer collections and scheduled backups carried over and is backing up just fine. Now, on the secondary server, in setting up replication, only some of the data has carried over and when trying to get replica setup to primary, the error message "The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))" keeps occurring. 

Please ensure the following steps are taken when making configuration changes and setting up replication between the Primary and Secondary servers:

1. Check for Active Users

   • Verify that multiple users are not simultaneously logged in to both the Primary and Secondary servers when applying configuration changes.

   • Having multiple active sessions can prevent configuration changes from being saved properly.

2. Limit to a Single Administrator

   • Allow only one person to be logged in on both servers during the configuration update.

3. Update Credentials on Primary First

   • Log in to the Primary server and update the required credentials.

4. Set Up Replication on Secondary

   • Once the Primary server credentials are updated successfully, proceed to configure replication on the Secondary server.

Following this process will help ensure that your configuration changes are saved correctly and replication is set up without errors.
