`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()`.
