To change the IP address of an Ensim server, modify the following files replacing any instance of the old IP address with the new one:
/etc/hosts
/etc/resolv.conf
/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/virtualhosting/namebased_ip_addrs
/etc/httpd/conf/httpd20_app.conf
/etc/virtualhosting/localnameserver
/etc/bind/options.conf.wp
/home/virtual/FILESYSTEMTEMPLATE/siteinfo/etc/resolv.conf
Reboot the server, then run the "NBDetectchanges"
/usr/local/bin/NBDetectchanges
