Engenius drivers cause persistent open ports

I uninstalled a Engenius wifi usb adapter driver pack on a win98SE box,
because I am changing to a wired network.
I see now in my firewall that there are still listening
open ports (from the previously installed engenius software) coming from
application "SYSTEM" for ports 137-139 with an assigned dhcp IP of
169.xxx.xxx.xxx.
How do I get rid of these open listening ports? Setting rules in the
firewall to block them seem to have no effect; neither does disabling
allowing dhcp in the firewall ruleset, the open listening ports still
appear. Did this Engenius driver software, which never worked, modify my
system files, such that I must now do a complete reinstall of windows to
close these open ports that do not seem to be effected by blocking rules
in the firewall set?
Is this not a security hazard and/or will in not interfere with using
other wired network hardware?
