AcceptEx() is a Microsoft WinSock v2 API that provides some performance improvements over the use of the BSD style accept() API in certain circumstances. Some popular Windows products, typically virus scanning or virtual private network packages, have bugs that interfere with the proper operation of AcceptEx(). If you encounter an error condition like:

[error] (730038)An operation was attempted on something that is not a socket.: winnt_accept: AcceptEx failed. Attempting to recover.

you should use this directive to disable the use of AcceptEx().
