I was having slow browser response in my Suse 10 system and discovered that of the three DNS servers I had listed the first was failing which cause slow name resolution even though once connected the connection was fast. I commented out the first DNS server in /etc/resolv.conf and everything was great for the next couple of days then suddenly my browser and email client started reporting "<domain-name> could not be found" errors for most sites. A few sites, the ones I visit regularly, still work but most don't. I've checked everything I know to check (which isn't a lot I'm afraid). My Linux box is behind two Linksys routers (a voip router and a wireless access point). I don't believe these are the problem because my Windows machine is behind the same two routers and works fine. The /etc/resolv.conf files contains references to the same DNS servers as the Windows box. The default gateway on the linux box is also set the same as the Windows box. I'm out of ideas and would appreciate any help you can give me.
