NTP setting: switch & computer

[ANOka_]

Hi!

I have a big problem, and i haven't found a solution yet, but I read the manuals and examples by the dozen.

I would like synchronize a 3Com 4200G switch clock to a computer via NTP.

The computer(s) is/are in a domain.

Switch fix ip is: 192.168.0.235

Computer IP #1: 192.168.0.100 (Windows XP with installed NTP server)

Computer IP #2: 192.168.0.252 (Windows 2003 domain controller)
