The best one can say for the message text is that it fails to distinguish
between two classes of underlying problem:
1.Failure to establish a TCP/IP connection
2.Failure in the authentication process

I would go further and say that the message text is misleading, in that
'server sign on' seems to refer to the authentication process. That seems
to be the way IBM support understood the message text, since their first
suggestion was to reset the password.

The explanation is even worse. It implies that the underlying problem
has to do with an intermemory connection between two components of the
z/OS server, not with any kind of communications between two servers.

It is not clear to me that support shares your view that they should
continue working with me; I reported the IP connectivity problem to them
almost two business days ago and have yet to get any response.
