Hi Stefan,

Thanks, I had not yet read that, but it tells me the same that I read on 
different places:

"Per default, Windows clients in an Active Directory, automatically 
synchronize their time with the DC, owning the „PDC“ role. If you don't 
want to use a different source, configure fallback time server, etc. you 
don't have to take action."

I have three DC's, all synced to NTP (and they all display the same 
result for "date"), pdc role is owned by DC2.

However... the time on the workstations is a minute off. So, even though 
they are supposed to sync automatically, we don't see it happening...

Are we alone with this, does it work in your networks..? (because then 
specifically we seem to have a problem)
