Are you sure about this?
I can't see how the NIS domain name is related to the hostname or for that 
matter DNS.

NISDOMAIN is not used in setting the hostname or the DNS domain name on a 
Redhat system.
I believe to change the hostame of a Redhat system you need to change the 
HOSTNAME= and possibly the DOMAINNAME= in /etc/sysconfig/network and 
restart your system.

The DOMAINNAME variable is set by config. programs but not actually used at 
system startup (as far as I can see).

Why restart?
Simply because so much stuff uses hostname or IP address related services!
