Have you ever faced any such errors while starting the Websphere server ?

Resolving the problem
Ensure that the naming resolution works for the host name. In the example, the name lookup failed for host name.Run the following two commands and ensure that they return the correct information.

nslookup `hostname`
nslookup

If both are fine try to create entries in /etc/hosts file by resolving the IP of the host.
some thing like below

 #
# hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem.  It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a
#               "named" name server.
# Syntax:
#
# IP-Address  Full-Qualified-Hostname  Short-Hostname
#
127.0.0.2       nc184120.tivlab.austin.ibm.com.tivlab.austin.ibm.com nc184120.tivlab.austin.ibm.com nc184120
9.48.184.120    nc184120 nc184120.tivlab.austin.ibm.com

Hope this will help solving ur problem
