Error 633: the modem (or other connecting device) is already in use or is not configured correctly. Any solution?

I have Microsoft Vista Home Premium edition. I use the data card (broadband +, model - HUAWEI EC1262) to connect to the internet.
I get error 633 whenever I try to use the data card to connect to the internet on my laptop. He says that "the modem (or other connecting device) is already in use or is not configured properly" and preventing me from accessing Internet.

I tried with a different brand of card data, but still getting same error. Map data even works on another laptop with Win7.

I did all the options like:
1 uninstall and reinstall modem drivers
2. release the COM port and the new port assigng

We always get but same error. Any solution for this problem would make.

Have you tried system restore? If you can restore the system to the date where it worked fine maybe it will work.

    Please provede me a permanent solution to this. I use Windows 7 Enterprise

    Hello

    1. If it works well before?

    2. what version of Modem drivers do you use? Do you have any other device connected to the computer?

    First of all, I suggest you to check if the modem is compatible with Windows 7.

    Check out the link:

    Windows 7 Compatibility Center:

    http://www.Microsoft.com/Windows/compatibility/Windows-7/en-us/default.aspx

    I would also recommend to connect the modem to a different computer and check if it detects there. If it does not work on another computer also, then the problem is with the modem and I would ask you to contact the manufacturer of the modem for any further assistance.

    Error 633 indicates that the port is already in use or is not configured for remote access dial out. You may need to check if the VPN and the connection connection try to use the same port that is causing the problem. You may need to check the settings of the modem and change the port for your needs.

    To work around this problem, use one of the following methods:

    Method 1:

    Reserves explicitly the TCP port that is used for the VPN connection. To do this, follow these steps:

    a. click Start, click run, type regedit.exe in the Open box and then click OK.

    b. in the registry editor, find and then click the following registry subkey:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters

    (c) in the Edit menu, point tonewand then click multi-string value.

    d. rename the multi-string value as 'ReservedPorts' and then double-clickReservedPorts.

    e. in the value data box, type1723-1723, and then click OK.

    f. exit the registry editor.

    Registry warning: this section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base: http://support.microsoft.com/kb/322756/

    .

    Method 2:

    Use the netstat command to find the program that is using port 1723. Then, end the process for this program. To do this, follow these steps:

    a. click Start, click run, type cmd.exe in the Open box and then click OK.

    b. at the command prompt, type the following command and press ENTER:

    NETSTAT - aon

    c. in the result which appears, identify the process ID for the program, if any, who is using the TCP port 1723.

    d. at the command prompt, type the following command and press ENTER:taskkill/pid PID/f

    Note: The taskkill command terminates the process that corresponds to the ID of the process. The/F option is used forcefully to complete the process.

    e. at the command prompt, typeexitand press ENTER to quit the command prompt.

    Restart your computer. This may cause the program that uses the TCP 1723 port to use a different port.

    I hope that helps!

    I've already reformatted the hard drive and the utility CD to reinstall the modem driver. Anyone got tips on how to solve the problem? An external modem would solve it?
    Either way, it's a satellite pro A10

    Hello

    If the HARD drive is formatted, use the recovery CD and reinstall the OS. After that, the modem must be recognized and properly installed. After that, configure Dial connection and check the modem. If the modem is not defective, it should work.

    The strange thing is that there is Error 633 which means: the port is already in use or is not configured for remote access remote calls.

  • Problem of password of account, without that we can connect to the network on this computer. The error indicates, "the trust relationship between this device and the network is no longer valid.

    Hi, I hope you can help with this problem. A friend has 6 computers networked to a Tower Server and have a problem. A worker student put computers into hibernation, and since then, nobody can connect to the network on this computer. The error indicates, "the trust relationship between this device and the network is no longer valid. I tried to get into the pc to try removing network and replace it, but I can't get on the Administrators account because it has been disabled. I'm at a loss on how to proceed. My friend cannot afford a service call, so I'll try to help him.  Thank you

    If the computer is on a domain then there are at least two accounts that can be used to remove the computer from the domain:

    • A domain administrator account.
    • A local administrator account.

    When your friend has launched Windows for the first time after buying the machine, he was prompted to enter the name of an account. This account is created automatically with administrator privileges. He should use it now.
