specific settings. In such cases there is nothing you can
do.
Your dialup settings may also change if you have Norton
Anti-Virus with the Auto-Protect turned on. If this applies
to you, turn off the Auto-protect and set NAV to scan
program files only.
You cannot disable an auto-configuration script in Internet Explorer

Go to IE tools/internet options/connection/dial up
settings/advanced dial up settings.
Make sure that disconnect when connection may no longer be

Go to Outlook Express, tools/options/connection and make

connection option of *any available*.
Next in Outlook Express go to tools/options/connection and
turn off *hang up after send/receive*.
