Where is WPAD DAT located in Windows 10?

Answered by Jarrod Smith

In Windows 10, the WPAD (Web Proxy Auto-Discovery) DAT file is typically located in the root directory of a web server. This file is used by web browsers to automatically configure proxy settings based on network location.

To locate the WPAD DAT file in Windows 10, you will need to access the web server’s configuration settings. Here’s a step-by-step guide to finding the file:

1. Open the Internet Information Services (IIS) Manager. You can access it by going to Start, then Settings, followed by Control Panel. In the Control Panel, click on Administrative Tools, and then select Internet Information Services (IIS) Manager.

2. Once you have opened the IIS Manager, you will see a list of available websites in the Connections pane on the left-hand side. Select the website where you want to locate the WPAD DAT file.

3. In the Features View pane, double-click on the MIME Types option. This will open the MIME Types configuration for the selected website.

4. Look for the “.dat” file extension in the list of MIME Types. The WPAD DAT file is typically associated with the “application/x-ns-proxy-autoconfig” MIME type. If you find this entry, it means that the website is configured to serve the WPAD DAT file.

5. Now, to locate the actual WPAD DAT file, you need to access the root directory of the website. In IIS, you can do this by right-clicking on the website in the Connections pane and selecting Explore. This will open the root directory of the website in File Explorer.

6. Once you are in the root directory, look for a file named “wpad.dat”. This is the WPAD DAT file that browsers will look for when auto-configuring proxy settings.

Please note that the above steps assume that you have already set up a web server and configured it to serve the WPAD DAT file. If you haven’t done so yet, you may need to consult the documentation of your web server software for specific instructions on how to configure the server to serve the WPAD DAT file.

The WPAD DAT file in Windows 10 is located in the root directory of a web server, and its MIME type should be set to “application/x-ns-proxy-autoconfig”. By following the steps outlined above, you should be able to locate the WPAD DAT file on your web server.
