I have configured my Windows 2008 R2 PDC so that will act as an NTP server. I have a Cisco ASA5510 that I also configured to use the Windows machine as its NTP source. I cannot see any errors on the Windows server, and the Windows Firewall is turned off. I can see that it is getting its own time from the external server I configured (pool.ntp.org) and it did change its own system time.
On the ASA when I run sh ntp status I get the following:
Clock is unsynchronized, stratum 16, no reference clock
nominal freq is 99.9984 Hz, actual freq is 99.9984 Hz, precision is 2**6
reference time is 00000000.00000000 (01:28:16.000 EST Thu Feb 7 2036)
clock offset is 0.0000 msec, root delay is 0.00 msec
root dispersion is 0.00 msec, peer dispersion is 0.00 msec
When I run sh ntp associations the following is returned:
address ref clock st when poll reach delay offset disp
~10.0.0.200 22.214.171.124 4 221 1024 377 0.7 254418 493.0
* master (synced), # master (unsynced), + selected, - candidate, ~ configured
The IP address of the PDC is 10.0.0.200 and showing as configured but not synced. I have set the PDC as the preferred NTP source as well. Has anyone sucessfully completed this before? any help would be much appreciated!
