RDP connection won't use the saved credentials for certain remote computers

I'm running Windows 10 and I'm trying to access a different Windows 10 machine via RDP. I saved the RDP file to include saving the credentials. Unfortunately for some machines this does not work. The username gets saved correctly but when I start the connection the first time without entering the credentials the login fails.

A login prompt is shown instead with the correct domain/username, with the error message that the login attempt failed. If I put in the password now the RDP connection is established correctly. Deleting the saved user credentials and trying to save them again results in the same problem. Even if I activate the check box "saved credentials", the next time I try to, it's back to the same problem.

I didn't discover any solution yet that would resolve the issue, any ideas?

Changing a GPO did the trick: on the client you are using to connect to the remote machine (not on the remote machine!):

• open gpedit.msc

• goto Local Computer Policy > Computer Configuration > Administrative Templates > System > Credentials Delegation.

• change the policy named “Allow delegating saved credentials with NTLM-only server authentication” to active

• add all remote computers to the list by adding TERMSRV/* (you can specify single machines and domains as well, see link)

• force a policy update by executing gpupdate /force

here's a good article about it with a few additional options.

Note: activating the policy named Allow delegating saved credentials wasn't necessary in my case
