Monitoring and Maintaining Cisco Unified MeetingPlace Web Conferencing
Configuring the Web Server to Synchronize with an NTP Server

Configuring the Web Server to Synchronize with an NTP Server
Cisco Unified MeetingPlace Web Conferencing automatically sets up the Windows operating system to 
use the Windows Time Service to synchronize its clock with the NTP server. This keeps the Web Server 
synchronized with the Cisco Unified MeetingPlace Application Server. 
You can also configure the Web Server to synchronize with an alternate NTP server. However, we 
recommend that all components in a Cisco Unified MeetingPlace system use the Application Server as 
their NTP time source.
Caution
Do not manually adjust the clock on the Web Server computer. Doing so could cause the Web Server to 
crash. To make a one-time manual adjustment, stop the Cisco Unified MeetingPlace Web Conferencing 
master service and restart it.
Note
If the time is not properly synchronized between the Web Server and the Application Server, web 
recordings may be either completely silent or the audio and web conferencing portions of a web 
recording will not be timed correctly.
Before You Begin
  •
Stop the Cisco Unified MeetingPlace Web Conferencing master service. See 
 in the 
 
module.
  •
Be aware of the following:
  –
By default, NTP uses UDP port 123. If your Web Server is in the DMZ and your Application 
Server is not, you will have to open UDP port 123 in your firewall for the default NTP 
configuration to work. The default configuration is the Web Server synchronizing with the 
Application Server as the NTP server.
  –
If you decide to use an alternate NTP server for your Web Server time synchronization, make 
sure that your NTP setup keeps the Cisco Unified MeetingPlace Application Server and Web 
Server perfectly synchronized. If the two servers are not time synchronized, certain features will 
not work.
  –
When you restart the Web Server, all manual changes made to the registry are lost.
Restrictions
Do not adjust the clock on the Windows computer while the web conferencing application is running.
Procedure
Step 1
Double-click the Window Time icon on the Windows system tray.
Step 2
Select the Internet Time tab.
Step 3
Select to automatically synchronize with an Internet time server.
Step 4
Specify your server name inside the Server: field.
