I am using eset smart security v4 under vista premium. Having problems with firewall miniport installation, i have desactivated this miniport then reinstall smart security v4. Now I can just discover the vistas pc in network discovery windows. When I stop the firewall, all my other machines ar visible. My pc doesnt share files any more with my other pcs. When I stop the firewall, the other pcs see my shares. Last problem : I can not change the ids options (by exemple show the blocked connexions). When I click on an option , then click on ok then if i come back to options the option i selected is no more selected. Excuses for my poor english I thank you by advance.
