Question : dns comes up mshome.net

Some machines on my network are acting weird. They loose internet and and when i do an ipconfig, the dns is mshome.net.
I can do a renew and it fixes the problem. I have a adtran 3305 running dhcp services. No windows dhcp on the network as far as I know. I am rechecking now just in case.
We run a few workgroups with various names, we are not in a domain.
Thanks in advance.

Answer : dns comes up mshome.net

try adding the domain name to the dhcp config and see if that doesn't take care of it.
