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

Is the server displaying the right time?

Follow this link to sync CM with NTP:

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 172.18.106.15 is my NTP Server

server 172.18.106.15 # Set Local Clock to Authoritive Time Source

fudge 172.18.106.15 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 172.18.106.15

Looking for host 172.18.106.15 and service ntp

host found : vnt-ntp.cisco.com

29 Sep 14:57:51 ntpdate[924]: step time server 172.18.106.15 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.
