Windows 7 Professional RDP Issue
I have a windows 7 machine that is having trouble connecting to Server 2008/2012.
I get this error: "An authentication error has occurred. The requested security package does not exits"
I undid recent updates, but this did not fix the issue.

What error do you get?
I use Windows 7 Pro 64-bit and Windows 8.1 Pro 64-bit to RDP into Server 2008 with no difficulty.
Is your machine the Pro version (not Home)?
Did you do all the recommended updates? Windows 7 sometimes left the .NET Framework in the Recommended category and you probably need the .NET updates installed.
Is your antivirus/firewall software conflicting? Try disabling it temporarily.
I still don't understand why this seems to happen on Win7 machines, but double check your registry:
Make certain tspkg appears on the list of 'Security Packages' in \HKLM\System\CurrentContro
ol\LSA, and add it if it's missing...
It's windows 7 Pro x64 with RDP v 8.1. All the RDP registry keys are there. The PC is fully up to date, including .net.

Did you try disabling the antivirus?
Also, set up a new Windows User Profile. Log in under the new Profile and test. The User Profile could be corrupted.
New user Prof and anti-virus didn't work either

Just curious, can you go into the control panel on win7 and open credential manager, is there an entry for the 2008 and 2012 server? If so, remove it and then reboot and then try again.
