Windows is packed with various useful features to ensure intuitive experiences, improve productivity and streamline workflow. Despite being a popular OS, there’re plenty of flaws that the system might encounter. One of the major flaws is the “Domain specified is not available” problem.
The error pops up when your computer is connected to a domain previously. If you try to reset the OS, the error restricts your login access to the system. This problem is quite frustrating because you can’t connect to the computer as you’re locked out of it.
Don’t worry. In this article, we’ll explain what causes the error and the proven solutions to solve this error.
What Causes the “Domain Specified Is Not Available” Error?
The error appears when a Windows user tries to log into a computer with a locked account in Windows Server 2008 R2-based Active Directory Domain Services environment.
The system behaves differently when logging in using a smart card instead of a username and password. If the computer is disconnected from the Active Directory Domain Services environment, this error message will occur while trying to log in.
Let’s check the potential fixes to help you in this situation.
Fix 1: Validate User Credentials
The error might arise due to some problems with authentication. You can view your credentials from the client certificate in the Certificate Manager tool. Open Run, enter certlm.msc and open Certificate Manager. Once you’re in, go to the Details window and check if your username is on the User Principal Names list. Also on the client workstation, check the event log whether it’s contacting the domain to confirm your credentials.
Fix 2. Set Your Account As Administrator
You may receive the login error if Windows thinks you’re using an unauthorized account. In that case, setting the account as an administrator can help solve this problem. To do it, you need to access Windows Recovery Environment as you’re unable to log into the account.
Here’re the steps:
- From your sign-in screen, press and hold the shift key and click the Power icon> Restart. Once the computer restarts, Windows Recovery Environment will be turned on.
- Choose the Advanced option in the Recovery Environment.
- Navigate to Troubleshoot.

Now, try to log in and see if the error still appears.
