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

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.
