We are having two servers clustered and recently I changed the IP address of one
of the Manage server.I was able to restart the admin server and other manage server
successfully.But when I tried to start the manage server of which the IP had changed
it threw some exception which is given below.

Currently this was done on development environment environment which is having
an evaluation licence ,but later this same process will be carried on all the
production servers which is having full license.So please let me know all the
effect of IP address change.

Note: I am having weblogic 6.1 with sp3 on both.
