Re: NTP CCM 4.1 Issue

Phones get their time from the Time Group configured in the device pools. Have you configured the right time there?

Re: NTP CCM 4.1 Issue


I follow the link, but when i try to use de ntpdate command the following message appear:


'ntpdate' is not recognized as an internal or external command,

operable program or batch file.


what can I do?

THanks in advance,


Re: NTP CCM 4.1 Issue

I usually follow the steps below and seems to work very good.

1. Go to \Winnt\System32\drivers\etc

2. Open ntp.conf in Notepad

3. Modify the file/content in their to reflect the NTP Server IP address.

For e.g is my NTP Server

server # Set Local Clock to Authoritive Time Source

fudge stratum 5 # Resets Stratum from default 3 to 5

driftfile C:\WINNT\system32\drivers\etc\ntp.drift # path for drift file

4. Go and now stop the Network Time Protocol Service

5. If you want you can now change the time on the box to hour ahead or back, to test if NTP will work or not.

6. Open command prompt and go to \Program Files\Cisco\Xntp

7. Type the command "ntpdate x.x.x.x" - Where x.x.x.x is the NTP server IP address.

C:\Program Files\Cisco\Xntp>ntpdate

Looking for host and service ntp

host found :

29 Sep 14:57:51 ntpdate[924]: step time server offset -10719.468824 sec

8. The NTP will update the clock/date, etc on the server and then should come back to the prompt again.

9. Go back and start the Network Time Protocol Service.

As you can see you do not type ntpdate on the root.
