ok i have looked up all the help on this soo far and have not found a solution yet that could solve my problem. my gentoo box can get to the internet via IP's but not though DNS. It is behind a nat router. Also this trouble started when i was setting up samba using this guide

What does the NAT router do, exactly ?
Does it allow DNS queries in both directions ?
Since DNS is mostly UDP, it won't easily cross a one-way NAT connection - you'd best forward DNS from the NAT router itself.
Or else add the standard ESTABLISHED,RELATED line to the NAT rules.
If that is at all possible.

Oh and drop the search line from resolv.conf until you have verified that it works...
What exactly happens when you type

Yes, I know what a NAT router does ;-)

Can you use dig ?
You need bind-tools for the nameserver tools.

You write that you cannot resolve hostnames.
This is not a samba-generated problem - it can't be.
It is in your network config somewhere, or in the network itself.
Dig (Domain Information Groper) can help you with name resolution problems.
All other tools (route, netstat, ping, traceroute) are already available.

i was thinking that it may be samba related as u have to modify permissions when u set up some of the other file with samba

ie

And.. er.. what does this have to do with network name resolution ?

Or with Samba, for that matter - that is an apache config snippet.

...which has nothing whatsoever to do with samba, and even less with the ability to resolve names on the network.
Where is this going ?
You keep saying Samba, I said no it has nothing to do with Samba; if you doubt that, fine.
You cannot resolve names on the network; I would concentrate on that instead of insisting that Samba must somehow be to blame.
