Hi Brian,

This is due to the new NLA code of rdesktop, your server presents it can do TLS but you do not have a certificate assigned to the RDP-tcp connection which will make rdesktop fallback to use non TLS eg. plain RDP protocol.

See following article how to configure a certificate for your server, http://support.microsoft.com/kb/895433, which applies on both 2003 and 2008.

Well, it appears I get a different result with the latest from svn..

Autoselected keyboard map en-us
Failed to connect, no valid authentication certificate on server.

I did discover that I can get a successful connection dropping back to RDP
v4 (-4).

Any thoughts to debug further?

Thanks,
Brian

Hi Brian,

What i can see is that ms13-029 issue is only related to the client and
update should not
affect the terminal service. However judging by your backtrace that is a
problem that was
newly fixed in upstream commit r1701 and will be included in next
release of rdesktop.

It would be nice if you could build rdesktop from upstream source and
verify that your issue
is solved with above mentioned commit.


Kind Regards,

Henrik Andersson
