Currently I am running Vista and for the last few weeks have been unable to reach certain sites such as msn.com from my pc. However I can access it from the library so I know it works. The pages takes forever then times out. Its not the firewall,I've scanned for trojans and viruses using several different avs'. What else can I try?

Try a different DNS server?

Hum didn't work.

One weird thing is if I use the DSL modem pages don't load, but if I use my wireless the pages load.
