I was hoping for some direction on this problem.  I have machines that are 
sitting right next to each other
on the same net accessing the same share. Most work but some get the 
Nullpointer below.

JVM - General Failure, rc=1

I have compared configs and  have trouble seeing any differences.  I seems 
things do not work at all without
a Dns server even when using Ip address.  I have seen trouble when  using 
a static Ip address . Any explanation of the sequence of events when 
trying to resolve a name would be appreciated.
