Is there somewhere i can download a patch for windows xp mstsc to support nla so i canconnect to my vista box at home?

No, at least not yet. However, it will be available when SP3 is release for XP during the first quarter of 2008.

As a work arounduntil the XP Remote Desktop client gets NLA functionality you might consider running Remote Desktop through a Secure Shell (SSH) tunnel and use a private/public key pair for authentication. SSH is very easy to setup by the SoHo user, IMHO... If you want to do that then I suggest using copSSH as the server install package of choice on yourVista desktopand Tunnelier as your SSH client. Tunnelier can be configured to automatically launch Remote Desktop session to one PC when the SSH tunnel is established. copSSH is actively maintained and updated when OpenSSH/OpenSSL/cygwin are updated... http://www.itefix.no/phpws/index.php?module=pagemaster&PAGE_user_op=view_page&PAGE_id=12&MMN_position=22:22 http://www.bitvise.com/tunnelier.html copSSH and Tunnelier configuration help... http://theillustratednetwork.mvps.org/Ssh/SecureYourcopSSHServer-Vista.html http://theillustratednetwork.mvps.org/Ssh/Configure-Tunnelier.html Make sure the XP Remote Desktop client and Vista Remote Desktop host are configured like this... http://theillustratednetwork.mvps.org/ScreenShots/XP/RDP6-XPClientSettings.jpg http://theillustratednetwork.mvps.org/ScreenShots/XP/RDP6-XPClienttoVistaServerConfig.jpg Good luck...

There is a patch and the patch permits several functions, first the salas xp patch permits 2 connections at the same time and the termserv patch permits as much as 200 connections at the same time with the windows xp and vistaremote desktop server to access the server over the internet all that is needed is port fowarding in your router and a small client from no-ip to convert your dinamic public ip to a static dns name e.g. http://cursosweb.sytes.net and thats all. Oh i almost forgot if you us the iis server builtin the windows os you can run your web server on port 80 and in your web page you could install the active x control that microsoft has made and does offer free of charge, so ther is no client that has to be installed in the clent machine all you need to do is open your internet explorer and from there you can make your connection. NOTE: patching the xp os system is not legal and i dont recomend that anyone installs the patch! it is for learning purposes only and not a replacement of the windows terminal server system!!!!!!!
