Network wizard

I had managed to network my Me computer allowing it to be
accessed from other xp comps on the network but the xps
could not be accessed from mine. I ran network wizard on
the XP computers and made a setup disk for my computer. I
ran this disk and restarted when prompted to. During boot
up windows asks me to wait whilst it updates my
configuration files. This fails with the message, cannot
update configuration files error loading %1 from %2
%1 %2. It repeats this infinitly.
Now my computer no wont start at all, not even in safe
mode. Is there anyway of bypassing the configuration
changes that it tries to make?? Thanks f***ing a lot
network wizard!
