RE: Windows 2000 DNS and iSeries

[Chris Bipes <chris.bipes@xxxxxxxxxxxxxxx>]

If all your PC use WINS or Windows Information Naming System, or something
to that effect, You can add a static entry into your WINS server for your
AS400 name to IP address.  A quick update to that works great for all new
connection going to the new IP / AS400.  This also keeps your AS400 out of
the very public DNS.  If you are not running WINS server at your site, then
DNS is the next best thing.  

Another Approach is to use a virtual IP with several routes defined in your
default router table(s).  You end the virtual IP on system A and start it on
system B.  A quick update on the router to change the primary route to
system B's static IP address.  Now you are not updating DNS or WINS that my
be controlled outside your company.

Good Luck,
