All,

I recently upgraded the music server I am running (the original XXHE PC, which by the way makes a GREAT music server) from Windows 8 to Windows 10 Pro.  I immediately ran into the CredSSP authentication error when trying RDC to audio PC (Mach III).

Sharing the fix, in case others run into the same issue.

- On the music server (the RDC client) run gpedit.msc
- Go to Computer Configuration > Administrative Templates > System > Credentials Delegation
- In Credentials Delegation you'll see a configuration for "Oracle Remediation Policy".  After my install of Windows 10, this was set to "not configured"
- Change policy to "Enabled" and select Protection Level to "Vulnerable" in the drop down.

Worked for me after this fix.

Gosh no idea but after reading again see what's happened.

My music lies on W10 pro I5 server now and all is faster.  

Music Server > Xxhighend Mach III> Dac > Pre > MinidspFlex > Monitors and subs. Best sound ever with minidsp as active crossover.

Robert,

Ever since the "Oracle" path was introduced in Windows, RDC sometimes has authentication problems if the client and server are not both updated with the security patches.  I've had this happen before when trying to connect to machines running older versions of Windows.  I'm guessing with audio PC running minimized OS, there might be issues with some machines establishing an RDC connection.  Just guessing.
