I did reactivate the Avast firewall.
Another oddity. My router is named Elsie3. That is the network it says my desktop is attached to. My laptop (the troubled computer we're talking about) says it is attached to Elsie3, whcih is good, but it says it is connected to Elsie2 at the top of the list that shows available networks.
Elsie2 was our previous rourter. Earlier today, I removed every available connection, then readded Elsie3. Elsie3 was listed at the top over the little picture of the house. After my most recent resart, it says Elsie2 at the top again, but it is connected in the list to Elsie3.
I think the fact that the desktop and laptop are convinced they are on different networks even though attached to the same router is messing with my ability to homeshare. That is another issue, though.
Below, I have pasted the results from the scan:
