> I replaced the forwarder (on my cheepo router) with google at and everything sprang to life. I've added my actual isp's server too.

It would likely be that your cheepo router doesn't properly conform to some standard regarding DNS replies. It would still be valuable to packet trace this to identify *how* a malformed response is killing samba. 

> Everything seems solid again now but could you have a quick look at this smb.conf. The addition of my isp's forwarder hasn't made any difference. Does the order matter? Can you even have more than one forwarder?

The order defines which forwarder is queried first, and will fall back to the second (presumably, this is how it works in BIND). Yes you can have more than one.
