time sync issue

Using Windows XP SP2, we are trying to time sync the computer clock with an external time source.

using regedit, we have changed the registry settings as per support.microsoft.com/kb/314054

net stop w32time works sucessfully
net start w32time works sucessfully

w32tm /resync /rediscover returns the following message: the computer did not resync because no time date was available

manual update of time via windows clock dialog box returns message: an error occurred getting the status of the last syncronisation. Element not found.

we can ping the ip address of the external time server

using w32tm /stripchart /dataonly /samples:5 /computer:xxx.xxx.xxx.xxx returns valid time differences of +12.43 seconds.

net time /setsntp:xxx.xxx.xxx.xxx - sucess
w32tm /config /update - sucess
w32tm /resync /rediscover - the computer did not resync because no time date was available

time server is working, we have a number of other domains connected to the time server which are sync.

im currently working on a windows xp computer, part of a workgroup, windows firewall disabled, which is physically connected via CAT5 cable to the time server.

the computer is not connected to the internet so cant verify with different time servers.

the stripchart command ip address of that of our time server, not local machine. so it seems our local computer and detect a correct time format from our time server as it identifying a +15 second offset.

any help would be much appreciated.

some of the articles in the above google search page say that windows time was never meant to keep really accurate time.

read thru several and judge for yourself.

Wish I could be of more help.
