Freezing by network connections

Recently, my Win98SE machine freezes, when another win98 or winXP
machine gets connected to the network, or it freezes during the boot
process at the moment where the network is loaded. When LAN cables are
disconnected, it works fine.

The only change preceding this behavior that I can remember was an
update of adaptec aspi drivers to version 4.7.

Any hints appreciated, Sven
