Enabling Network Level Authentication on XP Machine for Terminal Access

Great news to my Windows XP friends, if you are trying to connect to Windows Server 2008 or Windows Server 2008 R2 and you have been receiving the annoying message:

“The remote computer requires Network Level Authentication, which your computer does not support”

RDP Disconnected

There’s help and hope and here’s the solution from Aaron Thirling at http://mysupportportal.net/Cultrix/Knowledgebase/Article/View/37/0/enabling-network-level-authentication-on-xp-machine-for-terminal-access:

Configure Network Level Authentication

To enable NLA in XP machines; first install XP SP3, then edit the registry settings on the XP client machine to allow NLA

  1. Click Start, click Run, type regedit, and then press ENTER.
  2. In the navigation pane, locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
  3. In the details pane, right-click Security Packages, and then click Modify.
  4. In the Value data box, type tspkg. Leave any data that is specific to other SSPs, and then click OK.
  5. In the navigation pane, locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders
  6. In the details pane, right-click SecurityProviders, and then click Modify.
  7. In the Value data box, type credssp.dll. Leave any data that is specific to other SSPs, and then click OK.
  8. Exit Registry Editor.
  9. Restart the computer.

I hope this will help save you hours of frustration like I did trying all other solutions posted online.
