[Skimmertalk] Multiple Red Pitaya on network: -- now will not work

[Wes Cosand]

Thanks, Bob.

 I appreciate your help a great deal.

 I had tried most of that diagnostic methodology but with no success.  I'll
sleep on it and start again Monday.  My most successful thinking occurs in
the shower... chuckle...

I wish I had a network diagnostic tool better than Task Manager.
