[Wine] problem with DNS in wine - need help

[mishab]

Hi I am new to wine and looking for help.

I run wine 1.3.28 over Ubuntu 11.10 (32 bit).

I installed Firfox 7.01 - no problem during the instalation process, and the application loads fine.
But it seems that DNS does not function as I can't access any site by name only by IP.

The linux version  of Firefox (one that runs from ubuntu) works fine.

help aappreciated.
