Sorry that I don't have time right now for a more thorough answer.

Unfortunately, I don't think I ever found a clear-cut explanation for when you might get "Overlapped I/O operation is in progress". But I strongly suspect that the problem is one of authentication.

Before trying to connect to the remote registry, authenticate with the remote server either with something hackish like: 

    system("net use \\\\$Machine\\\$IPC");

#or, to be more eplicit (and get prompted for your password):
    system("net use \\\\$Machine\\\$IPC /user:domain\\you *");

or using Win32::NetResource's AddConnection().

There are also cases where SMB authentication will fail when using a computer name. So you might try using an IP address in $Machine instead.
