There is some CredSSP policy defaults change in May 8, 2018 Win10 update. This change may cause remote desktop login to fail. Of course only PCs that have been updated are affected.

Yes, it caused my RDC to fail...had to change the policy back to "vulnerable" to keep it working.

Hi guys,

What do we exactly notice of this ? how do we solve it ?
Of course I'm asking on behalf of (near) future issues for others with this.

Thanks !

Type "Group Policy" into the W10 search box and open up "Edit Group Policy".

In the left pane "Computer Configuration" then "Administrative Templates" then "System" then "Credentials Delegation" then in the right pane double-click "Encryption Oracle Remediation" and a new window will open.  In the bottom left pane on this window set "Protection Level" to "Vulnerable" and then ok out of everything.

That should do it.

Great, Anthony. Thanks.
Can you please elaborate on how this issue expresses itself ?
It could even be more important to know the exhibit than knowing how to solve it. So ... at some stage (could be a year after today) people receive a W10 update and suddenly ... [...] ?

Thank you again !

It is a policy change with the May 8 windows update.  All they changed was the default setting to a more secure one for such connections.  It affects RDC by RDC simply not working in our case, a failure to authenticate...instead an error box comes up saying something about CredSSP and an "authentication error" or some such thing.  Change the policy back to "vulnerable" as I posted earlier and it will all work again.

Hi guys,

I don’t update the Win 10 on the Audio PC but I had the same problem with Windows 7 updating in my music server. I have been unable to connect the music server to Audio PC via RDP since yesterday.

I will try the solution mentioned by Anthony on my Win 7 music server. Hope it works?

Will post results.

Best regards,

Hi Peter,
It would be ideal to find a solution that does NOT require to change group policy to "vulnerable". I think it will require some work on the host PC (mostly audio PC with specific older Win10 builds) so that the client PC will not have to fall back to a more vintage and vulnerable state.

Best,

Hi Anthony,

Thank you very much, it worked on my music server. Got the RDP connection back on.

Best regards,

Arvind

Good to hear Arvind. 

My MusicServer is connected to the internet but I use XXHE to make sure it does not update the OS so this May 8 update has not affected it.  When I am casual listening in my office I will RDC into the MusicServer from another (work) computer that does automatically update and thus was the one that was affected and the one that I had to reset the Group Policy. 

So if your MusicServer does not update (thanks to XXHE settings) then the only place a problem should occur is on the windows machine that is used to RDC to the MusicServer.

OK, so while the vulnerability exists for each OS, each OS also receives upgrades for it (I suppose not XP Wink). Good to know !
Man, 6 months back or so I had to install SP1 for a W7 machine (which controls the Audio PC over here) while for all this time I never ever applied any upgrade (KB) to it. I suppose I wouldn't know where to go without this information. OK, Google is your friend, but still.

Thank you for sharing this, Zheng.

Type "Group Policy" into the W10 search box and open up "Edit Group Policy".

In the left pane "Computer Configuration" then "Administrative Templates" then "System" then "Credentials Delegation" then in the right pane double-click "Encryption Oracle Remediation" and a new window will open.  In the bottom left pane on this window set "Protection Level" to "Vulnerable" and then ok out of everything.

This worked perfectly. Thanks Anthony.

Hi, I need some help. I can't find "Encryption Oracle Remediation". Please take a look to the picture sorry for the quality but I took it with my phone because I don't want to connect the Audio Pc to Internet.
