It turns out that I do have the resolver turned ON.  Somehow, I seemed
to have removed a line from the AndrewSetup file:
	AMS_ValidDomainSuffixes: .edu, .com, .bitnet
which supresses the warning message about hosts not existing if the host
name had one of these suffixes.

I played with the test program that Craig suggested I compile and run. 
It mostly gave me the results that a host was "indeterminate" which on
the program's yes-maybe-no answer scale is a maybe.  I thought name
resolution was more accurate than that, but I guess not.

For those interested in seeing the ouput from the valhost.test program,
here it is:
