SYMPTOMS

A Winsock application may cause a Stop 0x00000050 PAGE_FAULT_IN_NONPAGED_AREA error in Afd.sys.

CAUSE

The application passes a socket address length that is larger than the maximum socket address length in the TDI buffer in Afd.sys. The socket address data that goes beyond the MaxSockaddrLength overwrites the stack.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. This problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
