With Windows Vista and newer, when you enable remote desktop for administration, there are options to allow "Old Clients (less secure) [no network level authentication]" and "New clients (more secure) [with network level authentication]".

Is there any way to connect to the "more secure" version from non-microsoft clients? I've tried from the ubuntu client, and it works to connect to XP/2003 but it fails to connect to a Win7 Desktop or 2008R2 server, though I can connect to both of those machines from another Win7 machine.

Microsoft has documented the NLA and RD Gateway protocols; to my knowledge no OSS has implemented them yet however. I hoping someone knows of something however. – Chris S Jul 18 '11 at 15:56

There is a way now! The FreeRDP project has NLA support, but only in their git repo right now not in a stable version. They've had NLA support since late January if I remember right. The next stable version should have full support, but until then you'll have to compile your own.

Looks like it was announced on Jan 25th. – Zoredache Jul 18 '11 at 16:03
That looks good. Any pointers on how to get it up and running? My installation experience is limited to sudo apt-get install ;) – Nate Jul 18 '11 at 16:07
@NateBross Then this is probably not for you, since there are package dependencies that are hard to troubleshoot if you haven't done this kind of thing before. – sysadmin1138 Jul 18 '11 at 16:32
I'm always looking to expand my skillset, some guidance on getting started is all I'm really looking for, once I know the questions to ask I should be able to figure it out. – Nate Jul 18 '11 at 17:41
@NateBoss That tree has too many branches in it for me to do it justice here. Also, I'm not that familiar with Ubunbutisms so what I generate may not be useful anyway. – sysadmin1138 Jul 18 '11 at 20:37
