Starting the Synchronizer gives you a System.Security.SecurityException error in the logfile
Complete error: System.Security.SecurityException: The source was not found, but some or all event logs could not be searched. To create the source, you need permission to read all event logs to make sure that the new source name is unique. Inaccessible logs: Security.
This can be solved by adding the syncuser to local administrator group.
