It is the remote (client) end of the connection that runs identd; in
this case, that is the Microsoft box.

identd responds to a request to know who is trying to make the
connection.  It is inherently insecure, since you are depending on the
client end to tell the truth.  In the case of a Microsft system, that
seems very unwise!

Quite likely, in this case, the connection problem is because the
Microsoft box is not running an ident server.
