Socket write errors during authentication?

[nddipiazza]

I am getting some socket write errors during authentication.

Environment: I am using the DFS enabled flag, I am on Windows 2012 R2.

Note: I do not think this is related to #365 which refers to the .close operation throwing unwanted error noise in the logs.

I am on Windows operating system in this particular scenario.

I have seen Windows run out of sockets.... could that be related? What typically causes this?

This might actually be a side effect of whatever is causing this issue #420
