Meine Internet Explorer verbindet seit dem letzten Windows Update nicht mehr (Fehlermeldung: dnserror). Firefox, Email geht, jedoch andere auf dem Explorer basierende Software (z.B. Herr der Ringe Online, etc.) kommt auch nicht mehr ins Internet (Ich gehe direkt über ein dsl Modem ins Netz). Im Explorer selbst ist kein Proxy eingetragen.

An der Firewall (commodo) liegt es wohl nicht, denn die habe ich inzwischen
deinstalliert.

Ich probiere jetzt schon zwei Tage herum und weiss keine rechte Lösung mehr.
