mariner,
I agree with havesomeseichel that you seem to know your stuff. I have a different problem that maybe you know a solution for. Every once in a while I lose internet connectivity completely. IE will say the page is unavailable no matter what website I try and my email (Eudora) also can’t connect. I don’t know if the problem is with windows (vista), my ISP (optonline) or perhaps my free antivirus software (avast home edition), or maybe something else that I didn’t think of. The windows don’t freeze so I assume its not a RAM issue but I don’t know how to figure out what it is. The only way I know of to get back online is to reboot. That works every time. Any ideas?
