If you get synchronization problems, the following events are generated in the Windows Application event log (event source UserLock):
On the Backup server
- Warning event 400: The Primary server is not available.
- Error event 401: Check the description of the event to fix the problem.
On the Primary server
- Error event 402: Check the description of the event to fix the problem.
To avoid synchronization problems, it is highly recommended that both clocks - i.e. on the Backup and the Primary servers - are synchronized.
