Server 2003 is handing out wrong time via DHCP
This may be a very easy answer, however I need a quick answer here:

My DHCP server, also a DC, is handing out time that is 4 minutes behind.  Under the scope options I have 2 things set, "042 NTP Servers" which is pointing to 1 of our linux server in the DMZ (who IS pulling the correct time and is the linux NTP server) and I also have "004 Time servers) set to look at the same IP address.  Am I confusing something by having both of these set?  I copied these settings from the old DHCP server and everything was working fine before the transfer and even well after the transfer.  Someone just recently pointed this out and after quite some time playing, i cant get this set correct.

Any suggestions?

I would remove the time server and the pcs should sync from the domain.

Is this server a Domain Controller (or do you run an active directory domain?). I usually just set the W32Time client to connect to the address of the time server to synchronize time through Group Policy - it works for me.

There is a hotfix for that issue from Microsoft.

thanks for all of the solution, I will need some time to review and see what fixes the issue - if i havent already.... turns out that 1 of the other linux admins somehow turned off the service on the linux server that allows other apps to pull time info from it.

At the moment, it appears to be working again, but Ill review and see if any of these other issues seem to be the issue.

You should have your windows clients syncing time with the DC... best practice
The linux server and the DC will eventually "drift" apart in timing...  and if your windows clients/servers, get more than 5 minutes off...then you  can have alot of really quirky issues throughout the domain..

I always just use a logon script...   net time \\dcname /set /y
That way it is correcting the time every time a user logs on.

so here is where I am at:

Plug1, i tried this and it seemed to do nothing different.

tigermatt, I looked at this, and as this seems the closest to my issue, the only way I found to set up win32time was a bunch of registry edits, and in the documentation I found it didnt specify at what point to specify the external server.

youngrmy, this didnt seem to be the issue.

xuserx2000, to clarify my situation, my windows clients sync with my windows DC which syncs with my linux server.  

For some reason, even after having the linux admin make the appropriate change, im still not getting the correct time.   I manually set the time on the DC which then updated the correct time to my clients....something is obviously still not set right.  Also my DC's are not external pointing, therefore I have to point them to an internal source.

Thanks

On the DC...go to command prompt..

type:

net time /querysntp

This will output the source your dc is currently configured to sync with.

If it is not correct...

type:

net time /setsntp:{ipaddressofthelinuxserver}

Then type..
net time

...see if you get an error message....for example..."could not locate a time-server"

check the event log for any errors...
