In the Windows Explorer of computer #4 (win98), when I clicked on Win7 computer #3 it asked for a password which I couldn't get past. The result was the same when I tried [tools][map network drive]. So back in Computer #3 I set "password protected sharing" off. Then I was successful with [tools][map network drive] to map computer #4 to the \users\ folder in computer #3. The same with mapping to #2 and #1. Now all four computers are accessible from each other. Everything seems to work.
