I'm suppose you're using PPP and pppconfig for the dialup connection.
If so, check your pppconfig setup for that connection. Make sure that
"Nameservers" (advanced options) is set to "None". If set to "Dynamic"
or "Static", a script in /etc/ppp/ip-up.d messes with your resolv.conf
when the connection comes up. Likewise, a script in /etc/ppp/ip-down.d
messes with it when the connection is brought down. Note that the latter
script is also run at boot time from /etc/init.d/dns-clean.
I haven't really had problems with the way this works, but in your
particular situation this might cause problems.
