Startup the Tivoli desktop on either the client or server and select the
icon for the policy region.  When the policy region GUI comes up, select
either the client or server icon.  If the client icon is selected, press
the right mouse button and select the option Configure-->Remove Server.
If the icon for the server is selected, press the right mouse button and
select Configure-->Configure TME10 Netview Clients-->Remove client access.

Once the server has been removed from the client and the client has been
removed from the server, repeat the steps adding them back using the
hostname of the client or its fully-qualified domain name.  Both should
resolve to the new IPaddress of the client.
