I use Connection Keeper [Freeware: registration is appreciated but not
required]
Works with all versions of Windows® 95, 98, NT4, 2000, ME, XP, and
2003.
Can be set to automatically redial if the connection is lost.
Can automatically close popup windows that ask the user if they want
to stay online.
Can be minimized to the system tray so that it does not take up space
on your taskbar.
Can run when you are not even connected to the Internet. It waits
patiently until you connect before it does anything.
Uses very little computer resources.
The query that is sent to the ISP takes up almost no bandwidth. You
can run Connection Keeper in the background regardless of whether or
not you are using the Internet without fear that your connection will
be slowed down.
The interval at which Connection Keeper queries the ISP is adjustable,
or it can be set to a random interval.
You can choose whether or not Connection Keeper requests a real or
bogus URL. You have full control over the real URL's that are
queried.
If you are a webmaster, Connection Keeper can be used to monitor your
web site. It will let you know if a page is not downloading properly.
Errors can be reported by a popup window or by email.
Command line parameters can be used to close a specific popup window.
Command line parameters can be used to check for the existence of a
file. A message window will only appear if there is a problem. This
is useful for checking the status of your network when your computer
boots up, for example.
Command line parameters can be used to download a web page and report
any errors that occur. This is useful for checking the status of your
web site when your computer boots up, for example.
Connection Keeper installs no spyware and displays no advertisements.
