The message is coming from dcerpc_util.c, so it probably has nothing to
do with dns

You are using Bind, so, as the 'dns forwarder' line will be ignored, you

I think we need to know more about your set up, OS versions etc.

Also I would take it as a big favour if you found a better email client
that didn't add all the blank lines ;-)
