I have a Windows 2003 SP2 server ( it is bascially just a file & print server ) that loses it's abiility to update / communicate with our sntp server in the domain ( which is our pdc emulator ).

I tried manually configuring the sntp settings ( via regedit ) to fix this issue.  All seems fine after the reg hack, no more warning nor errors in the System Log for about an hour or so.  However after that this cycle event 38, 29, then 47 reappears.  I made sure all the servers in question are patched.  I have looked and do not see any obvious network commmunication errors.  So, I am baffled at this point to what might be causing this.  Any ideas ?
