    How to lock out a modem? (Windows XP Pro, fully patched)

    I have two modems on my system. One is an internal WinModem on my main phone line. The other is an External modem on my line 2 ( for internet). The problem I'm having is that, even though I have the external modem set for my ISP dial up, on occasion the system does not detect it, and automatically reverts to the internal WinModem and dials out. (locking up my main phone line). Is there any way to lock out that modem so the system cannot use it without first ASKING? I use it on occasion for faxing out on my main line while still online on line 2, so I don't want to take it out, I just don't want the bloody system to use it for internet dial up, unless it's an emergency and I specifically WANT it to.

    The most radical solution: swap the phone lines and turn off an external modem until you need it...

    Otherwise check settings on your Internet connection each time before using it. The main cause that your computer doesn't detect an external modem - you turn on the modem AFTER you power up the computer.

    Kaplinb:

    Thanks for the suggestion, however I use the External modem for the internet, because it's faster and takes less resources than the internal modem. Also the External modem is not a fax modem, just data only. I require the internal modem to interface with the Microsoft Fax Driver.

    As regards checking the internet settings each time, this is not a solution which would work well. This computer provides a central internet connection for my machine, my wife's machine, and my daughters machine, thus it must be set to dial out when it is prompted. If i were to change the setting to manual, it would make it much more difficult to use from all three machines.

    The External modem powers on when the power strip is switched on. I think the occasional non-recognition is something else. Possibly the port just doesn't see the modem at times, when the machine is booting into Windows. Since the modem is powered from the same power strip as the computer, it's certainly on when the computer is.

    In any case, I would still wish/hope for a solution that would allow me to prevent the computer from accessing the internal modem unless I wish it to, if such is possible.

    Thanks again. Anyone else have an idea?

    What about disabling the internal modem (in Device Manager)? Then, when you (or others) want to connect to the internet, the external should be recognized and used. Then, on the occasions when you want to use the internal for faxing, enable it again. Not a very elegant solution, but it might indicate whether or not there is a problem with the external modem not being recognized.

    This might be overkill, but it appears that it will do what you want and can be configured so it won't interfere with anything else. I found this information, "WebPI's Modem Access feature allows you to block modem access entirely or during specified time periods during the day. here. The program's homepage is here and it's free to try, $25 to buy. Pretty reasonable for a stealth monitoring program that also has the ability to block modem access.

    I have an external BB connection, but use an internal V56 modem to update my website - it's an ISP thing. After using dialup I occasionally find that the internal modem is used by default which sounds like your problem.

    Basically I have a short lead that carries the line from the internal modem to the front of the machine and a second lead from there to the phone socket. When I've finished with the internal modem I disconnect the line to the phone socket. No inadvertant connection can then be made using the wrong connection.

    This also protects me from premium line rogue diallers - my brother got stung for

    To Rebel: Your suggestion is good, and I tried it before, however XP is so Bloody-Minded re autodetection, and it just reinstalls the modem again automatically after each reboot

    To Doc: Thanks for the suggestion, I'll download that one and try it out.

    To Gfamily: that may be my best solution, and I'll use it in the interim.

    Thanks all for your help!

    That's strange. Are you Disabling the modem or Uninstalling it? If the latter, then Windows will redetect it at the next boot, but if you disable it, it should not.

    Sounds to me like an external ADSL modem plus a connected internal dial-up modem, and it sounds like you have them set up correctly. The problem is that you have them both turned on. I suggest you go to Control Panel, Internet Options, Connections, and set the Never Dial A Connection option. The external modem is treated as part of a LAN and is 'always on' unless you turn it off or unplug it. If you must do so, then dial up manually to send a fax or to receive one if you know it's coming. Don't forget that long-distance charges apply to that type of fax if the number it is sent to makes it so.
