How to Use Guide: VZAccess Manager - Troubleshooting

    1. I can no longer browse web pages when connected to any network after:
      • Installing AOL
      • Applying a Service Pack
      • Making any changes to my network configuration such as installing a Network card.

        Venturi uses a feature from Microsoft called Layered Service Provider (LSP). If changes are made to your network configuration it is necessary to uninstall and reinstall Venturi's LSP. You can uninstall Venturi from "Add/Remove" programs in Windows® control panel and then reinstall it to restore normal operation or you can follow the instructions below to just uninstall and reinstall Venturi's LSP:

        To uninstall Venturi's LSP:


        1. Right click on your "Start menu and select "Explore" to open Windows Explorer.
        2. Browse to C:\Program Files\Venturi2\SPI by doing the following:

            1. In the left pane of Windows Explorer, click on "My Computer".

          1. In the right pane of Windows Explorer:

            1. Click on your "C:" drive.
            2. Double click on the "Program Files" folder.
            3. Double click on the "Venturi2" folder.
            4. Double click on the "SPI" folder.
        3. Double click on "Uninstall Transparency".
        4. Select "Start", choose "Shutdown", and then click "Restart" to restart your PC.

        To re-install Venturi's LSP:

        Repeat the above instructions but in step 3, double click on "Install Transparency".

  1. After installing Venturi or another application, I can no longer browse web pages connected to any network or I get a blue screen on start up.
    • Typically this is caused by an existing conflicting application that is using a feature from Microsoft called Layered Service Provider (LSP), sometimes also referred to as transparency. Venturi uses LSP by default but can be reconfigured to eliminate the use of LSP to resolve the conflict.
    • For more details see section on Explicit Proxy Settings on how to do this.
  2. When trying to use Venturi, I can't browse web pages wirelessly.

    1. Uninstall Venturi from "Add/Remove" programs from Windows Control Panel.
    2. Select "Start", choose "Shutdown", the click "Restart" your PC.
    3. Verify you can browse web pages wirelessly, if not, and this is a corporate PC - look for a Winsock Proxy icon in Windows Control Panel or check with your network administrator to see if your company is using Winsock Proxy software on your PC. If this is the case, it must be turned off to access the Internet directly when connecting via the Verizon Wireless Mobile Broadband, NationalAccess or Quick 2 Net (14.4 kbps) connection.
    4. If you can browse wirelessly with Venturi removed, there is probably a conflicting application on the PC using Microsoft's Layered Service Provider (LSP) technology. You can reinstall Venturi and then reconfigure it to eliminate the use of LSP to resolve the conflict. For more details see section on Explicit Proxy Settings on how to do this.
  3. I can't get Venturi to coexist with other applications I use.
    • This is vary rare but you also have the option of using the Venturi compression servers for improved web browsing in a clientless mode, eliminating the need to install the Venturi compression software on your PC. See section on Clientless Option.
  4. I use a personal firewall and I am not sure what settings are required to allow Venturi to work.
    • VentC.exe should be granted permission to listen for data from the localhost and to send/receive data to the internet. VentC.exe listens on the following ports: TCP 8000, 8001, 9875 and UDP 8008. It connects to the Venturi server on UDP port 29301.
    • Ventcfg.exe should be granted permission to listen for data from the localhost and to send/receive data to the localhost. Ventcfg.exe listens on UDP port 8007. It communicates with VentC.exe on TCP port 9875.
    • With most personal firewalls controlling Internet access, you will only need to select "Yes, always" when prompted to allow VentC.exe to connect to the Internet.
