NIS domainame not holding after reboot

["Waldher, Travis R" <Travis R Waldher boeing com>]

I’ve had a few machines, especially virtual ones for some reason; that just don’t hold the domainname after a reboot.

 

I type:

 

domainname mydomain

 

and it’s set.  I edit /etc/sysconfig/network and add NISDOMAIN=mydomain.

 

I reboot and I get (none) when I type in domainname.  Even odder, if the machine changes NIS domains, it’s remembering the old domain.

 

Has anyone seen this?
