Cannot Update Group Policy

Question

Hi,
I am trying to update group policy on computers, I am getting this same error on all computers. I am to ping Windows Server from all computers. Need Help

Computer policy could not be updated successfully. The following errors were encountered:

The processing of Group Policy failed. Windows attempted to retrieve new Group Policy settings for this user or computer. Look in the details tab for error code and description. Windows will automatically retry this operation at the next refresh cycle. Computers joined to the domain must have proper name resolution and network connectivity to a domain controller for discovery of new Group Policy objects and settings. An event will be logged when Group Policy is successful.
