I'd recommend you get a copy of an SNTP client and just run that. Never 
need to think about it again :-) and it also means that file creation / 
write times etc. will be correct.

See overview and various options at 
http://geodsoft.com/howto/timesync/wininstall.htm
I'd agree with his recommendation for 
http://sourceforge.net/projects/nettime/

If the Dell machine spends much time disconnected from the Internet, 
you'll want a full NTP client, rather than an SNTP one (full NTP 
calculates the drift factor and continues to apply that even when it has 
no connection). In fact, at 10 sec per hour, you may want an NTP client 
anyway, so you don't need to query too often.  I haven't personally 
tried the Meinberg solution linked from the first page given above, but 
it looks worth trying out.

btw - recent Windows include a limited version of SNTP - but it's so 
limited it won't help you. I think it's limited to checking once per 
week - I've heard a rumour of a way to get around that, but a quick 
search didn't turn anything up.
