Remote Desktop Client doesn’t use stored credentials

The problem

When I’ve to connect to the same development machine over and over again using RDP I store the credentials.

But when I later connect again I’ve to still provide a password.

After entering my password 1387 times in the last year I started searching for the reason why it doesn’t use my stored credentials. As it turns out this is because of a local policy.

The solution

1. Start “GPEdit.msc” and navigate to “Computer Configuration\Administrative Templates\System\Credentials Delegation”

2. Open the policy “Allow Saved Credentials with NTLM-only Server Authentication” (or “Allow Delegating Saved Credentials with NTLM-only Server Authentication” for Windows 7)

3. Select “Enabled” and click on “Show”.

4. Enter the server where you want to connect to with the stored credentials. You’re allowed to use wildcards, so I choose “TERMSRV/*.int” (my development machines are always in a domain ending with “.int”).

5. Close the screens and run “gpupdate”.

Now it’s possible to connect to the server without providing the same password over and over again.
