Elements using specific Organizational Units as validation logic are not working and "No AD Site Defined" line is detected in SLTrace.htm file. (4298886)

When using a Validation Logic that includes membership to specific objects in Active Directory the element is not applied.

In the SLTrace.htm file these lines are detected:

11:13:25 Querying Directory Services for Computer site...
11:13:25 Could not determine computer site by querying Directory Services
.
11:13:28 --[ Active Directory ]--------------------------------------------------------------------------------------------------------
11:13:28 Active Directory Site         = No AD Site Defined

Verify the the Active Directory site information and the status of the Netlogon service. This can be checked either via command prompt or through PowerShell.

1. PowerShell method to perform a WMI Query:

• Open a PowerShell window.
• Enter the following command: Get-wmiobject -class win32_ntdomain

This should return the clientsitename and dcsitename.

     2. Command line method using the Nltest command:

• Open a command line window.
• Please type this command: nltest /server:Yourmachinename /dsgetsite

Note:  in the syntax above, please replace the string "Yourmachinename'" with the name of the affected machine.

The command should complete successfully and return the site name. If an error is returned like "Getting DC name failed: Status = 1919 x77f ERROR_NO_SITENAME"* this means there is no site information in the registry for this machine. The site information is recorded in the key called DynamicSiteName in the registry: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters\DynamicSiteName, if the DynamicSiteName is empty the error* above will be returned. 

Also, the NLTEST command can be used to output a list of the domain controllers and their Sites:

• On a CMD window please enter this command: NLTEST /dclist:domainname

     3. Check the status of the Netlogon service:

• Open a command line window.
• Please type this command: sc query netlogon

If the service is stopped then please start it and run the Desktop Authority script on the affected machine to see if the issue still stands.

4. If the user machine is using WIFI or it's using a VPN and it's on a different network, the No AD Site Defined message can appear in the sltrace due to missing Subnet information not set in the Active Directory Sites and Services console. 

If any or all these tests fail, the issue is with the Windows environment and not Desktop Authority.
