At the command prompt type "NET TIME /QUERYSNTP"
That will return a value if a time source is defined.

Check under  HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Parameters

That should be NT5DS

Let the windows time hierarchy do its job, great article from Matt  http://tigermatt.wordpress.com/2009/08/01/windows-time-for-active-directory/

Thanks

Depends on a number of factors.  If it is only a single Windows 2003 server, then sosinc3 is correct.  If this server is a member of a domain there could be number of time sources.  The best way to confirm the time source is to use:

net stop w32time
net start w32time

After the w32time service has restarted - you should see an event 37 in the System log identifying which time source the server is using and if it is receiving good time from that source.

If you're having time problems the best way to reset the system to defaults is to use:

net stop w32time
w32tm /unregister (you might have run this twice)
w32tm /register
net start w32time

W32tm /monitor

Look at the "RefID" value.
