Scenario 1: Updated clients cannot communicate with non-updated servers

The most common scenario is that the client has the CredSSP update installed, and the Encryption Oracle Remediationpolicy setting does not allow an insecure RDP connection to a server that does not have the CredSSP update installed.

To work around this issue, follow these steps:

  1. On the client has the CredSSP update installed, run gpedit.msc, and then browse to Computer Configuration > Administrative Templates > System > Credentials Delegation in the navigation pane.
  2. Change the Encryption Oracle Remediation policy to Enabled, and then change Protection Level to Vulnerable.
