Cisco Unified MeetingPlace, Release 7.0 -- How to Resolve Web Server Time Synchronization Problems
Main page: Cisco Unified MeetingPlace, Release 7.0
Up one level: Troubleshooting
If the time on the Cisco Unified MeetingPlace Web Server is different than the time on the Cisco Unified MeetingPlace Application Server, many symptoms arise, such as the following:
- Scheduling and joining web meetings may not be honored
- Recording voice and web meeting files may not be synchronized properly
- Playback may not be possible
- Other time related symptoms may be seen
If the Web Server is part of a Windows domain, the web software overrides the domain NTP default settings.
In Windows, go to System > Eventlog to see W32tm information and errors. This tells you which NTP server the Web Server is syncing with. Once you find the NTP server, use the following command from a DOS prompt to check if there are any communication issues between the Web Server and the NTP server:
w32tm /monitor /computers:x.x.x.x
Note: This should be the IP address of the Application Server or the shared IP address in a dual Application Server configuration.
If the time is more than 30 seconds off, the Web Server will not sync with the Application Server which is synched with the corporate NTP server. Perform the following:
- Stop all Cisco Unified MeetingPlace services.
- Stop the Windows Time Service.
- Update the time.
- Make sure that the time difference between the Application Server and the Web Server is less than 30 seconds.
- Start the Windows Time Service.
- Start all Cisco Unified MeetingPlace services.
- Check the eventlog to make sure that the servers are syncing properly.
