Hi, today I accidently changed one option of Teminal Services, I checked "Allow connections only from computers running Remote Desktop with Network Level Authentication".

After that, I can't connect to my server any more. The error says: The remote computer requires Network Level Authentication, which your computer does not support.

But my client pcs(both home and at office) are running Windows 7, as far as I know, it shoud support NLA; And in About dialog of Remote Desktop Connection there says "Supports Network Level Authentication".

My server is running Windows Server 2008, placed in IDC center; I could connect to it before I change the settings. All other sevices(like IIS, SQL Server) are running normally. For clients, I tried two PCs running Windows 7, and two virtual windows XP machine running in Virtual PC and Virtual Box, all of them gives the same error message. Is there a way I can make things right without go to IDC which is far away?

Thanks.
