In this case, I was pretty sure that the credentials were correct. Even they worked fine with other machines but one of my machines start throwing this error.

If you’re also facing same issue, here’s how to fix it.

FIX: ‘Your Credentials Did Not Work’ For Remote Desktop Connection In Windows 10/8/7

FYI: Security Policy and Group Policy snap-ins are not available in Windows 10 Home edition. If you’re on Windows 10 Home and want to use these snap-ins, go here and upgrade to Pro edition. This fix will only work on Windows 10 Pro, Enterprise, Education editions.

FIX 1 – Via Security Policy Snap-in

5. Repeat step 4 for following GPO settings as well at same path mentioned in step 2:

  • Allow delegating default credentials with NTLM-only server authentication
  • Allow delegating default credentials

6. Make sure Deny delegating saved credentials GPO setting at same path mentioned in step 2 is set to Not Configured.

Close GPO snap-in and you can then run gpupdate /force command or reboot your system to make changes effective.

Then check if your Remote Desktop Connection is working. You’ll find that issue is resolved now and you can connect systems remotely without any issue.

  • For me (Windows 8 ThinkPad), the issue was with my registry editor compatibility level. Steps to resolve: 1) hit the windows key +R and type “regedit” 2) Navigate the file path: Hkey_Local_machine\system\currentcontrolset\Control\ 3) Click on LSA 4) Click on “lmcompatibilitylevel” 5) Change value to 3 and you should be good to go!
