You do know that squeeze is EOL ?

I would suggest removing the 'domain' line, it is turning off the
'search' line, you cannot have both lines in resolv.conf

This is very likely your problem, /etc/hosts should be:

127.0.0.1	localhost
10.18.66.5	pdc.wmpny.local	pdc

and as you have '127.0.1.1', this probably means you are using
Network-Manager, if so, stop this from using dnsmasq.
As you are using '.local', I would also suggest turning off Avahi, if
this is running.
