JohnnyBeGood,
I'm sure I would have had a ping response, because the computer was showing in the Network folder on both my other computers. I also was controlling keyboard and mouse functions on it through InputDirector, which is over the network. It just restricted me when I went to open the Network icon for the computer. I solved the problem by changing two values in the registry. I had tried everything else I found in forums and I probably worked on it about five hours before these two changes worked:
In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
I changed:
restrictanonymous from 1 to 0
and
LimitBlankPasswordUse from 0 to 1
Both changes were necessary.
Then I went back and reversed the failed efforts I'd made. I removed Network from my Properties>Security list I'd added on the three drives and on a folder I was using to test. Then I went and removed two registry keys that were suggested would solve the problem, and also the two Users I added in Local Securities Policy. I also removed a couple of entries in the Credential Manager I tried. It was a back breaker of a day, but the computer is available on the network now.
I have no idea if the uninstalling of AVG had anything to do with it, in case I owe them an apology.
