|

While working remotely through Active Directory Domain Services (AD DS) environment, you try smartcard logon, but the message appeared- ‘The system could not log you on. The domain specified is not available. Please try again later.’

Generally, it happens when you disconnect the PC from the AD DS environment and log on again. 

So, what can you do now if the error message appears?

How to Fix the ‘Domain Specified Is Not Available’ Issue

Fix the Logon Error

Whenever you try to log on to the AD DS environment but cannot get access, you need to check the validity of the issue first. To do that, you have to type on the target command prompt- ‘certutil dcinfo verify’. If the message appears, then you can follow the fixes described below-

  • Validate the credential
  • Hotfix

Fix: Validate the Credential

The problem may remain in the authentication. If so, you need to validate the domain. To do that-

Firstly, you have to open the client certificate. You will get it from the certificate manager.

Then, you have to switch to the ‘Details’ tab. While scrolling down, you will find a certificate extension named ‘Subject Alternative Names ’.

Here, ‘User Principal Name’ containing an authoritative domain with a logon user name would exist. You will get it while checking.

Finally, the client workstation might contact the specified domain to validate the credential (certificate authentication). Here, you need to check the event log. After doing that, you might get the related info from the domain controller or client controller.

Alternate Fix: Hotfix

A hotfix can be an alternative system to fix the domain-specified issue. Microsoft serves a supported hotfix. However, it is available only for a Windows Server 2008 R2-based Active Directory Domain Services (AD DS) environment. 

So, if your existing server supports hotfix, the message- ‘Hotfix download available’ may appear. If you don’t find it, contact the Microsoft Customer Service and Support section.   

Final Words

Commonly, the possible cause of the issue is, the cached account might be disabled on the computer for logging out. As a result, the operating system deleted the credential.

So, if the issue arises, you can follow the described fixes or take customer support from either the client or domain controller.
