To create an extra synchronizer service you have to copy the file 'Install extra service' from the Exchange Synchronizer\Prerequisites folder into the Exchange Synchronizer folder. From here you can run the file to create the extra service.
In case you get a Unauthorized Access Exception while executing the batch file there is a rights issue. This can be solved easily by running the file as an administrator.
You could also create a new service entry through the registry. The path is “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\InfoBridge Synchronizer”
For example, you could create a new service "InfoBridge Synchronizer Rank2".
