I am having a combination of both problems, the one stated in the original post and the recent post. I am using Windows 98SE and a different wifi adapter than the ones stated. When I plug in the wifi adapter, the system freezes. Ctrl-Alt-Del shows msgsrv32 frozen. When I end that task, system becomes unfrozen and I can actually use the wifi for a few minutes before system hangs completely. Have to power off and on to reboot at that point. The few minutes I can actually use wifi varies, often less than 5 minutes but never longer than 20 minutes. I've had both msgsrv32 and the complete hang happen with and without all the latest unofficial updates installed. Still haven't found a solution. So frustrating.
