How to rename DSfW netbios name

6. Do a xadcntrl reload.

Make sure the new netbios is availble by doing a nmblookup.

Below is a script that will change the netbios name for the FRD and ADC DSfW servers.  Simple create a file called change_netbios.sh, cut and paste the following, change the permissions on the file to be executable, and get a kerberos ticket before running the script.

touch /root/bin/change_netbios.sh
chmod 755 /root/bin/change_netbios.sh
kinit administrator

#!/bin/sh
