This article applies to  Windows Server  scenarios. Scenario Let’s assume that you have two organizational units in your domain: OU-TSSERVERS OU-SUPPORT In  OU-TSSERVERS  units, there are computer accounts, and in the  OU-SUPPORT  units there are users accounts.

GPO process

Processing a GP steps by step procedure: The client performs Internet Control Message Protocol (ICMP) slow-link detection to a domain controller in its site to determine link speed. In Windows Vista, the use of ICMP for slow-link detection is replaced by the Network Location Awareness (NLA) service. The client reads CSE status information from its local registry to determine which GPOs were processed last. The client uses LDAP to search the gpLink attribute in Active Directory on each container object within its location in the Active Directory hierarchy—first at the OU level (including all nested OUs), then at the domain, and finally at the Active Directory site level. From the results of this search, it builds a list of GPOs that must be evaluated for processing. Each GPO is then searched in Active Directory to determine whether the client (user or computer) has the necessary permissions to process it. Its version number, the path to the Group Policy Template (GPT) portion o
