Configuring Proxy Settings for SystemLink

    Last Modified: March 31, 2021

    Configure SystemLink to work on a network that uses a proxy server between your internal network and the Internet. Doing this ensures your systems can access feeds from NI Package Manager.

    You can only configure proxy settings for Windows systems. Also ensure both the server and client machines have Internet Explorer installed.
    1. Clear any existing proxy settings on your system in the following files:
      • C:\Program Files\National Instruments\NI Package Manager\Settings\nipkg.ini
      • %localappdata%\National Instruments\NI Package Manager\nipkg.ini
    2. On your SystemLink server, download Sysinternals PSTools and extract the ZIP archive.
    3. Open the command line utility as an administrator and navigate to the extracted folder.
    4. Enter one of the following commands:
      • psexec64 -u "nt authority\network service" -i cmd.exe for the network user, which handles Systems Management
      • psexec64 -u "nt authority\system" -i cmd.exe for the service user, which handles Package Repository
      A new command prompt opens running as the corresponding user.
    5. In the new command prompt, enter whoami to verify the user.
    6. Enter C:\Program Files (x86)\Internet Explorer\iexplorer.exe to launch Internet Explorer.
    7. In Internet Explorer, under Settings, click Internet Options» Connections» LAN Settings.
    8. Enable the Use a proxy server for your LAN checkbox and enter your proxy server information.
    9. Enable the Bypass proxy server for local addresses checkbox.
    10. If you configured the client to connect to the server using an IP address or fully qualified domain name (FQDN), click Advanced and add an exception for the hostname for your server.
    11. If the command prompt asks for additional proxy credentials, enter cmdkey /generic: <proxy-server-ip> /user:<username> /pass:<password>.
    12. Complete these steps for both the system and network service user.
    13. On each client machine, complete these steps for the system user.
