Boot Camp-Win XP wont sychronize with time server

Win XP and Leopard are both running smoothly, however winXP wont synchronize with the time server and I have to manually set up time every time I boot up. Also, when I boot back into Mac Leopard; the time is displayed incorrectly until I click on the clock to open the dialog box which seems to refresh the time and then I have the correct time again. Can someone please help resolve this problem?

I should probably add that when I was using bootcamp with Mac OS X tiger I had the exact same problem and I had hoped that Leopard would fix it but was unlucky with that. Also, I have installed all Mac drivers from the leopard CD; I can browse the internet.

Simple answer, no fix.

Turns out OS X reads the system clock differently then Windows does, so there is no real permanent fix, but I managed by doing the following:

In OS X, set your clock to sync with the servers in your time zone. Then, in Windows, make sure that same setting is OFF. I'm in Vista, so I have an option to set up a secondary clock, so I just played with the time zones until it matched up and all was well. I don't remember if XP can do this though, so you should look into a 3rd party app that can.
