Thanks. The problem stems from the issue that SYSTCPD in the TCPPROC is not 
being used by RESOLVER. In fact, SYSTCPD in TCPPROC is worthless as it is 
shipped.

Seems terribly confusing to have this in the sample proc provided by IBM just 
to find out that it doesn't do anything. 

We have a solution, or at least a workaround. We'll continue to add SYSTCPD to 
every job that needs RESOLVER and will someday build an MVS proc for RESOLVER 
that can use GLOBALTCPDATA.

A difference in name resolution almost certainly stems from a difference in TCP 
parameters. Check what's in your batch JCL, your logon proc and your Unix 
scripts.

There has been discussion on IBM-MAIN in the past on the priorities of the 
various sources for TCP configuration data, and it's documented in the CS 
manuals.
