Windows 8.1 w/Update 1 ignores WPAD DHCP Option 252 RRS feed

  • Question

  • Hi!

    We try to roll out Windows 8.1 w/Update 1 and Internet Explorer 11 with the lastest updates installed. The clients are configured to autodetect proxy settings in IE with WPAD DHCP-Option 252. The clients are not allowed to query WPAD in DNS.

    No problems with Windows 7.

    In NetMon I can see the DHCP Request with the following result

      - WPAD: - Type 252
         OpCode: Web Proxy Auto Detection (WPAD), 252(0xFC)
         Length: 30 (0x1E)
      + End:

    But the Windows 8.1 client still tries to use name resolution

    NbtNs:Query Request for WPAD   <0x00> Workstation Service

    The same issues with WindowsToGo with Windows 8.1 w/Update 1.

    Any ideas? We tried a lot with Troubleshooting Automatic Detection on but nothing helps. Thanks!
