Domain Controller Unable to connect to the Time Server

G

Guest

Hi,

We have a domain controller that has a problem syncronizing to an external
time server. I tried almost all the solution posted in this forum and to
other forum in the Internet and still it does not work.

I also tried to use the command w32tm /unregister and w32tm /register to
reset all registry entries for w32time service but still it can't connect to
the time server.

I look at the firewall and the policy allows udp 123 to the time server and
their are no logs coming from my DC on udp port 123 going to the time server.
I used ethereal to captured the packet when I command w32tm /resync, but I
could not see any udp 123 request going to my time server.

On the DC, I command

C:\WINDOWS>w32tm /resync
Sending resync command to local computer...
The computer did not resync because no time data was available.

c:\w32tm /monitor
ICMMADB.DOMAIN.COM *** PDC ***
ICMP: 0ms delay.
NTP: error WSAECONNRESET - no server listening on NTP port

C:\WINDOWS>w32tm /monitor /computer:icmtnzaw5
The following arguments were unexpected: /computer:icmtnzaw5
Exiting with error 0x80070057

To add up to my problem, there is no events log on Windows event viewer, the
last w32time log that I had was last sept 29, 2007 @ 4:10:49 PM.

Event id: 36 - Last received 9/29/2007 @ 4:10:49 PM
The time service has not synchronized the system time for 86400 seconds
because none of the time service providers provided a usable time stamp. The
time service is no longer synchronized and cannot provide the time to other
clients or update the system clock. Monitor the system events displayed in
the Event Viewer to make sure that a more serious problem does not exist.

I activate the debug log of w32time, hope you can better analyze the problem.
