SYMPTOMS
When you run a custom Winsock network program on a Microsoft Windows XP Service Pack 2 (SP2)-based computer, you receive the following error message:

Error 10055 = WSAENOBUFS

An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.

Note The error message that you receive may be different depending on the program that you are using.

This symptom occurs if the Windows XP SP2-based computer does not have network connectivity.

The English version of this hotfix has the file attributes (or later file attributes) that are listed in the following table. The dates and times for these files are listed in Coordinated Universal Time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel.   Date         Time   Version        Size     File name 15-Aug-2005 23:58  5.1.2600.2739  360,576  Tcpip.sys 15-Aug-2005 23:46  5.1.2600.2739   30,720  Arpidfix.exe



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. . /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 &quot;Applies to&quot; 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.
