Answer 1

It seems that you were running two applications, and they are trying to access the same socket.

What Microsoft says about your problem:

WSAEACCES (10013)

• Translation: Permission denied

• Description: An attempt was made to access a socket in a way that is forbidden by its access permissions. For example, this error occurs when a broadcast address is used for sendto but the broadcast permission is not set by using setsockopt(SO_BROADCAST).

  Another possible reason for the WSAEACCES error is that when the bind (Wsapiref_6vzm.asp) function is called (in Microsoft Windows NT 4 .0 Service Pack 4 [SP4] or later), another program, service, or kernel mode driver is bound to the same address with exclusive access. Such exclusive access is a new feature of Windows NT 4.0 SP4 and later, and it is implemented by using the SO_EXCLUSIVEADDRUSE option.
