Driver issue on bootcamp now

Question

I have bootcamp on my mac and am having a driver issue.  When I switch from mac side to bootcamp, I have to uninstall and reinstall driver to get on internet. Wondering if I did something to cause this issue? can't seem to fix.  Was working previously. Now, I cant switch and get on internet on windows side without uninstalling/reinstalling NVIDIA driver.

Once you have XP installed, it is independent of BC. My suggestion is to try the 4.0.4033 drivers.
From Bootcamp.xml file for 4.0.4033 (there is also a 64-bit version in the same package).
