name server/internet connection problem

i am having trouble connecting to the internet using netscape. I have set my http and ftp proxy to the correct IP addresses and know the IP address of my name server but i get 2 errors whenever i open netscape.

1st error: unable to locate server

2nd error: There is a name server problem. If your site must use a non-root name server you will need to set the $SOCKS_NS enviroment to point at the approiate name server.

Any ideas where i should start?

Thanks
