On some machines the InitializeSecurityContext() will return SEC_I_INCOMPLETE_CREDENTIALS during TLS handshake. That case is not handled, it will try to continue reading, thus blocking until timeout. The handling of this case would be to repeat the InitializeSecurityContext once again, or as we do here, inform to use a client cert if available.
