CredSSP encryption oracle remediation error using RDP

Anonymous

If this has been covered, I ask that someone point me to a solution. I have the following two devices:

Workstation with Windows 11 24H2

Laptop with Windows 10 22H2

When I try to RDP to my WS from my Laptop I get the CredSSP error. The solutions I found online recommend changing the group policy

Administrative Templates>>System>>Credentials Delegation>>Encryption Oracle remediation>>Enabled

I've tried the same three options on each of the computers at the same time. For example Vulnerable on each, Mitigated on each and Force Updated Clients on each.

Some help to resolve this would be most appreciated as I occasionally like to RDP to my WS from my laptop when I am in another room.

I have another issue with my Windows 11 WS. I will create a second thread for this.

Thank you.

    I have resolved my own issue. I went to sysdm.cpl>>Remote

    Uncheck "Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)

    This was checked on my Windows 11 and Windows 10 computers.
