[Solved] Unable to connect with Dev box Error code: 0xd07

Hi folks,

Recently, I ran into a frustrating issue while trying to connect to my development box. Out of the blue, the system refused to let me in and threw an error that blocked my access. If you've ever been in the middle of a project and suddenly lost access to your VM, you know how disruptive this can be.

After some trial and error, I found a solution that worked—and I’m sharing it here in case it helps someone else facing the same problem.

Error message: 

Remote Desktop Connection

As a security precaution, the user account has been locked because there were too many logon attempts or password change attempts. Wait a while before trying again, or contact your system administrator or technical support.

Error code: 0xd07

Extended error code: 0x0

Solution: 

Step 1: Try a Full Stop and Start (Not a Restart)

First, I tried restarting the VM from the Azure portal, but that didn’t help. What worked was stopping the VM completely and then starting it again. This seems to reset some internal state that a simple restart doesn’t touch.

Step 2: Use an Alternate User to Regain Access

If the stop/start method doesn’t work, the issue might be with the admin account being locked. In that case, you can log in using an alternate user account. You can find this user’s credentials on the LCS (Lifecycle Services) page under Environment Details.

Here’s how to proceed:

• Log in to the VM using the alternate user.
• Open the Run dialog (press Win + R) and type: lusrmgr.msc
• This opens the Local Users and Groups management console.
• Find the admin user, right-click on it, and select Properties.
• Uncheck the option that says “Account is locked out” (or similar).
• Apply the changes and try logging in again with the admin account.

Other Recommendations: 

1. Add the other user in Admin group once your admin account is enabled, this will give you more control on this when needed. 

2. You can also install Account Lockout Status for further troubleshooting on why account is getting locked

3. While you are unlocking Admin account, also set 'Password never expire' option this will disable the option itself of account getting locked.
