You can't.Network Level Authentication is only possible in Windows XP when ServicePack 3 is installed.You needthe Remote Desktop Connection Client 6.1and you need to enable the CredSSP functionality (introduced in ServicePack 3) in the registry or through Group Policy. More information: XP SP3 Network level authentication a myth? Description of the Credential Security Service Provider (CredSSP) in Windows XP Service Pack 3 Description of the Remote Desktop Connection 6.1 client update for Terminal Services Alternatively you couldupgrade to / installWindows Vista.
