I agree with you in managing servers with SCCM, that leverages WSUS and I also follow the common sense of applying changes on a test ring and after a positive result move to the next one.
Set it to Enabled, and set the protection level to Vulnerable. Edit the following setting: Encryption Oracle Remediation. Navigate to the following path: Computer Configuration > Administrative Templates > System > Credentials Delegation. To set the protection level to Vulnerable via Group Policy, follow these steps: However, it will expose the servers to attacks. It will allow you to connect to servers remotely using RDP. Vulnerable: This is the lowest level of protection. However, services that use CredSSP will work. Mitigated: This level blocks applications such as the Remote Desktop Connection to connect to servers that do not have the update. Thus, do not choose this option before applying the update to all of your clients and servers. Force Updated Clients: This is the highest level of protection because it requires applying the update to all clients you are going to communicate with using CredSSP. The Group Policy setting you need is Encryption Oracle Remediation. You can do this either via Group Policy or by changing the registry. However, if you need to connect to a computer that hasn't received the update, you can downgrade the protection level to Vulnerable. Once all servers and clients are patched, be sure to undo this setting.Īs always, keep those servers patched and up to date but be sure to test.To solve this issue, you have to install the update on the servers. Windows Registry Editor Version 5.00 “AllowEncryptionOracle”=dword:00000002 If patching the client or server is not in the cards, the other easy fix is to apply this registry setting to temporarily bypass the check. The best way to solve this issue is to ensure both client and destination have the latest patch installed so that RDP can be secure in it’s connections. The issue stems from a patch that went out that addressed the CredSSP vulnerability. Microsoft put this blog post out on the 11th to address it : 
Each of them was throwing up this error when trying to connect to them! Based on email threads and twitter, it looks like this is bothering quite a few people/clients. This environment used a VPN connection and then RDP connections to various servers that I needed. I ran into this over the weekend connecting to a customer’s environment. Have you seen this error pop up when you are attempting to RDP to a machine?
