We all know that the Group Policy Engine updates the whole architecture of group policy every 90 minutes. So when we configure a GPO setting, this time we have to wait until the setting is applied to clients. Clients may also need to log out and log back in to make the settings effective.

If we need to update the GPO architecture immediately after applying the parameter, we use the gpupdate /force command. Using the /force parameter allows us to immediately update the GPO at the user and computer level. This change applies not only to new or modified GPOs, but also to older GPOs.

However, sometimes executing the gpupdate /force command does not update the GPO engine. We have recently solved this problem on our Windows server. The following message appeared when we decided to update the GP engine :

The processing of Group Policy failed because of lack of network connectivity to a domain controller.

Fix Errors in the DNS Configuration

An invalid DNS configuration can interfere with other important operations on member computers, domain controllers, or application servers in this Active Directory forest, such as login authentication or access to network resources.

You must resolve this DNS configuration error immediately so that this domain controller can resolve the IP address of the source domain controller using DNS.

The DNS protocol on the same:

The DNS server could not complete the directory service enumeration of the local UGATL-MAIN.local zone. This DNS server is configured to use the information obtained from Active Directory for this zone and cannot load the zone without this information. Verify that the Active Directory is working properly and repeat the enumeration of the zone. The extended error debugging information (which may be blank) is “”. The event data contains the error.

Opening the Local Group Policy

Okay, so the first thing to do in this situation is to introduce a local security policy. We can do this by pressing the Windows + R key to launch the Run dialog box, and from there copy and paste the secpol.msc file and press Enter.
