Polycom – NTP Settings – Sound Point 501 IP SIP Phone

Here is what I used for my Polycom NTP settings.  Central time zone.

SNTP tcpIpApp.sntp.resyncPeriod=”86400″ tcpIpApp.sntp.address=”″ tcpIpApp.sntp.address.overrideDHCP=”0″ tcpIpApp.sntp.gmtOffset=”-21600″

Setup NTP Windows Guest OS – Vmware – Windows 2008 R2

Here is what I used and it worked great, I just did this on 3 domain controllers which are resided on the same vm host.

w32tm /config /manualpeerlist:us.pool.ntp.org,0x8 /syncfromflags:MANUAL

net stop w32time
net start w32time

Test using this:

It will tell you time source and when it last synced.

w32tm /query /status

If you mess up the config and want to start over do this:

net stop w32time
w32tm /unregister
w32tm /register
