The sign-in method you’re trying to use isn’t allowed [Fixed]

Hi, ever been locked by your own computer? Then, you received this message? "The sign-in method you're trying to use isn't allowed". If your answer is Yes, you are on the right track. I am going to tell you the solution. Previously, same as other, I also have been stuck to this problem. I've spent lots of time for searching the right answer. But, this guy have the most complete answer wrote in social.technet.microsoft.com. My thousand thanks for him. 

Symptom: When trying to logon a computer using non administrator ID, you may receive this message: "You cannot log on because the logon method you are using is not allowed on this computer. Please see you network administrator for more details."

Case 1: Group Policy' "Allow log on locally" was not setup to allow users or domain users. To setup allow users or domain users to logon the computer or domain, you need to add the users or domain users to the "Allow log on locally". Please follow these steps to add the users.

1. Run gpedit.msc.
2. Expand Computer Configuration\Windows Settings\Security Settings\Local Policies
3. Click on User Rights Assignment
4. Ensure that "Allow log on locally" includes Administrators, Backup
Operators, Domain Users or Users.

Case 2: Group Policy' "Deny log on locally"  was setup to deny users or domain users. To setup allow users or domain users to logon the computer or domain locally, "Deny log on locally" should be empty or no users or domain users in the list. Please follow these steps to remove the users or domain users from the "Deny log on locally".

1. Run gpedit.msc.
2. Expand Windows Settings\Security Settings\Local Policies
3. Click on User Rights Assignment
4. Ensure that "Deny log on locally" is empty.

Case 3: The local group policy allow user to logon. However, domain group policy which overrides local policy doesn't allow users to logon locally. The resolution is modify the domain policy to allow users to logon locally.

Case 4:  The domain policy allows domain users to logon locally, but the local policy doesn't and the domain policy doesn't apply to the computer. The fix is running gpupdate to force to update the domain policy.

Case 5: Norton Firewall blocks the communication between the client and domain controller. The solution is disabling Norton firewall or re-configuring it to allow to access the domain controller.

Hope It helps!

In my case, I got this problem because I've installed a software that changed my permission in registry. I only can logon to my Administrator with new fresh desktop but couldn't log in to my own account.  My account just vanished! It was not there in login screen. Then, I checked on my Group Policy. I noticed that my account got disabled. Here, a screenshot I got from Google. 

Then I checked on the "Deny log on locally" policy, I noticed that my account has been denied to log on and I just removed my account from the list.

>Click on the user and click Remove button. I restarted my laptop and I saw 2 user in login page. I enter my password and Puff!! Magic happened! Thank God, I've succesfully entered my old desktop. :)

Thanks for reading. ^_^
