On my C drive I have slowly encountered a problem where when I am connected to the internet on my dialup I will lose the ability to use the connection. This will happen anywhere from minutes to hours into a session. I have more than one isp dialup provider and this will happen to any provider I have. I have an Agere/Trendnet external modem.
When I am connected and lose my ability to use the connection it will still show that I am connected and listening to phone I will hear "modem sounds".
I am using Windows XP Professional
