DNS Error Problems.

[fredde]

Hello everybody.
I had absolutely no problems connecting to the internet until today. I am using the sys. in my sig. When trying to connect to any web site, either with IE or Firefox, I get a dsn error. If I connect using my MSN logon I have no problem. After I use the MSN software both IE and Firefox connect most of the time. I use verizon dsl and connect via a router. Any suggestions PLEASE.

Thank You
