Thanks for the advice man. I just was having that ventbios(01) problem and your solution fixed it quickly and easily. Way to go. Not only did your advice help me fix my computer, it also helped me figure out how to get rid of all that junk I didn't want on my taskbar taking up my system resources in the background.

the best cure would be to right click on "network neighborhood"

you will see a list of protocols and clients..

find your network adapter and remove it..

then go to control panel "system properties"
or right click "my computer" and go to hardware/device manager.
find your network card.. then remove it..

shut down windows and then reboot..

if you still have a network adapter in place..
windows should give "found new hardware"
and ask you for a drivers disk..

supply the drivers disk for your network card.. if you don't have one.. perhaps windows will have one for it..

if it cannot be found or downloaded.. then you may want to removed the card..

if this does not cure the problem..
you can always go to add remove programs..
then windows programs..

and uninstall any network file sharing.. and reinstall it if needed
AFTER A REBOOT..

this SHOULD cure the problem..
if it doesn't..
you may try reinstalling windows overtop of itself as a last resort.
or a fresh install.

good luck.

but I'm going to say this is a driver issue.
