Leave the existing list of security providers intact and add credssp.dll to the end of it. Click OK. Close Registry Editor and reboot the machine for the change to take effect. When the Windows XP machine reboots, it should be able to successfully establish the RDP connection. Note: There is no support for NLA or CredSSP in Windows Server 2003. Therefore, you will be un
