Sometimes I just can’t leave well enough alone
At this precise moment all three computers have Net connectivity and can talk to each other. It was all working a bit earlier but somehow it messed itself up again. (I ended up just installing NetBEUI just to get them all to talk to each other. Every time XP wante to create a “Network Bridge” everything just fell apart again.) For the past half-hour, the new laptop has been attempting to connect to AOL every time it needed to do a DNS lookup. That seems to have stopped itsel with several release/renews on the router along with many reboots of the laptop.
It’s late. It’s working. I’m going to bed.
