Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This problem was first corrected in Windows 2000 Service Pack 2.
This behavior can occur, for example, when process A calls WSADuplicateSocket() and then passes the resulting structure to process B by using an interprocess communication. If process B is currently creating a duplicate socket by means of a call to WSPSocket(), a second call to WSPSocket() before the first is complete may stop both the socket duplication code and the program.
