I have seen this before. In my case, the \000 was courtesy of Windows
2000 DNS/DHCP server. Something to do with Active Directory, I think.
It's being added because your dhcp client is requesting a
domain-search-path, and Win2k's DHCP server is providing it. (corrupted
as it is.)

When you connect to your other network, the DHCP server is not providing
another search path.

If you're using dhclient, modify /etc/dhclient.conf to override
('supersede') the domain-search-path with what you want.

If you're using pump, add 'nodns' to /etc/pump.conf to stop pump from
updating /etc/resolv.conf

If you're using something else, check the man pages.
