RDP CredSSP encryption Oracle remediation fix

When attempting to RDP to another server the following error is displayed:

clip_image002

Edit the registry to create the following:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\CredSSP\Parameters\AllowEncryptionOracle  with a Value of “2”

clip_image004

Note: you may have to create the CredSSP and below structure.

This issue may also go away if all your servers and workstations attempting RDP connectivity are up to date on the same latest windows updates. The solution above is a workaround till all patching is completed.

For GPO deployment to multiple systems see article below:
