Go check and see if you have installed windows
updates to your system.I had the same problems about a
week ago,and i restored my system to just before the
updates were installed and that solved my problem.The
updates were (windows xp Q817606, windows xp KB823559 and
windows update V4)these were automatic updates from
microsoft around 7-9-03.If you try this and it fixes the
problem,hopefully it will,drop me an e-mail and let me
know,i would like to know if this is what corrected my
problem or if it was something else.

Good Luck
