[Samba] time server - slightly OT

[Chris]

Many of the XP systems shipping today come pre-configured to keep their 
clocks in sync by communicating with one of Microsoft's SNTP servers, 
and will apparently automatically use a local AD server if available, 
as well.

The "net time" command can be used to change the systems to use a local 
NTP server as well.

I'm wondering this:
If the firewall redirects ntp traffic from the Windows boxen (that are 
attempting to get to one of MS's SNTP servers) to a local NTP server 
will the WIndows systems properly time sync? Or will it not work 
correctly because, without a specific setsntp:x.x.x.x, it will be 
looking for exclusively for an SNTP server?

Thanks.
