Okay,

        I have to admit I have not a clue what Ray is telling you here as
the format of a record in the windows "hosts" or "lmhosts" is "The IP
address should be placed in the first column followed by the corresponding
host name." (See hosts.sam or lmhosts.sam).   If you are having problems
resolving addresses then regardless of how you resolve the IP address at the
workstation you will have issues, and entering an address in the OS/400 host
table is not going to resolve a client connection issue, at least based on
my experiences.

    But, this is the first question are you having issues resolving the IP
address, or is there an issue with routing the IP address.  When you have a
Win/2K system fail to connect what tools have you used before you start the
reboot / recovery process you documented.  Tracert ? netstart -r ? ping ?
What's the result ?

    Next, if you have 800 planned Workstations assuming at least two
connections to the host per workstation, I would STRONGLY suggest you stop
and look at
http://www.as400.ibm.com/tstudio/tech_ref/tcp/routing/routing.htm
as you are most likely in a switched multi collision domain configuration
and need both load balancing for your work loads, and most likely Virtual IP
addressing for your HA fail over process.

    Good Luck, and PLEASE keep us updated on your progress....
