Error 10013 (WSAEACCES) is perfectly legitimate.

"Another possible reason for the WSAEACCES error is that when the bind function is called (on Windows NT 4.0 with SP4 and later), another application, service, or kernel mode driver is bound to the same address with exclusive access"

10048 (WSAEADDRINUSE) says:

"Typically, only one usage of each socket address (protocol/IP address/port) is permitted. This error occurs if an application attempts to bind a socket to an IP address/port that has already been used for an existing socket, or a socket that was not closed properly, or one that is still in the process of closing"

Reference :

Perhaps the binding to actual IP address (127.0.01, or local interface) you use will result in one of the errors, and binding to would result in the other (depending of course on the conflicting bind)

Regardless though, Graham found his victim :)

The problem was that the "World Wide Web Publishing Services" was running.
You should have got the error 10048 Socket already in use. You reported
error 10013. Strange.
