To work around this problem, install the Microsoft Loopback Adapter.

To install the Microsoft Loopback Adapter, follow these steps:
  1. Click Start, and then click Control Panel.
  2. If you are in Classic view, click Switch to Category View.
  3. Click Printers and Other Hardware.
  4. Click Add Hardware, and then click Next.
  5. Click Yes, I have already connected the hardware, and then click Next.
  6. Click Add a new hardware device, and then click Next.
  7. Click Install the hardware that I manually select from a list, and then click Next.
  8. Click Network adapters, and then click Next.
  9. In the Manufacturer box, click Microsoft.
  10. In the Network Adapter box, click Microsoft Loopback Adapter, and then click Next two times.
  11. Click Finish.
Note After you install the Microsoft Loopback Adapter, you can manually configure its options. If the TCP/IP properties are configured to use the Dynamic Host Configuration Protocol (DHCP), the Microsoft Loopback Adapter eventually uses an autonet address (169.254.x.x/16). The Microsoft Loopback Adapter eventually uses an autonet address because the adapter is not actually connected to physical media. By default, TCP/IP properties are configured to use DHCP.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

This problem occurs in the custom Winsock network program when you try to join the computer to a multicast group. Specifically, this problem occurs if you try to join the computer to a multicast group by adding a multicast address on the network adaptor. The error message is generated when you call the Winsock setsockopt function with the IP_ADD_MEMBERSHIP option. The error message is generated even though you have disabled the Media Sense feature in Windows XP.
