Change the BypassProxyOnLocal Configuration

If Visual Studio stops responding when a user runs a query in Team Explorer, you might need to reconfigure Internet Explorer so that it does not send requests for local network resources through a proxy server. If your organization uses a script to configure Internet Explorer, some of the settings that it contains might cause this problem.

  • If your organization does not require the script, you should configure Internet Explorer to ignore the script and detect network settings automatically.

  • If your organization requires the script, you might be able to update it to avoid this problem.

  • If you cannot ignore or update the script, you should set the optional registry key, BypassProxyOnLocal, for HKEY_CURRENT_USER (per user) and HKEY_LOCAL_MACHINE (global) to true. This configuration causes the computer to request local resources without going through the LAN proxy server.


    If you set BypassProxyOnLocal to true, you might also improve performance when you run the tf.exe command-line tool.

By default, BypassProxyOnLocal is not configured, and all URL requests are routed through a proxy server when Internet Explorer is set to use an automatic configuration script or to detect settings automatically. If you configure this key and set it to true, a URL request is routed through the proxy server only if the requested resource is outside the organization's intranet. If the resource is inside the organization's intranet, the request is not routed through the proxy server. In these local requests, the URI does not contain a period (.). For example, a browser entry of https://webserver/ would not be routed through the proxy server. However, a browser entry of would.


Incorrectly editing the registry might severely damage your system. Before you change the registry, you should back up any valued data on the computer.
