Time Synchronization Windows 2003, 2000, XP to Cisco 2821 Router
Posted on 2006-03-30
Yes! It's time for yet another time sync question...
I have this working in my environment now, but have a few questions.
I modified the Domain Default Policy GPO which works great at the desktop level but seems to have no affect at the server level:
One Windows 2003 servers, I modified the registry (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters) NtpServer and Type strings. I also typed the NTP Server IP address into the "Date and Time Properties | Internet Time | Server" field and checked "Automatically synchronize..."
On the Windows 2000 servers I used the "net time \\servername /setsntp:x.x.x.x" command and stopped and restarted the W32Time service.
1. What is a good stratus 1 time server IP address I can use? I'd like to use a DNS name, but am not sure how well that will work from the router. How can I compare the time at this server to my environment to ensure accuracy?
2. Why won't the GPO work on the servers? Can I modify it or create another one to work for them? I want all devices to NTP off the router.
3. Are the things I've done as listed above sufficient for the servers? I still see some discrepancies.
4. Do GPO settings override the registry settings at the desktop level? I can still see NTP registry setting that do not match the GPO.
5. I'd also like to setup our Avaya phone switch to sync with the router. Anyone done this before?
6. Can I get consistency throughout my environment using this methodology and without having to buy additional equipment?
