Event Id1129
SourceMicrosoft-Windows-GroupPolicy
DescriptionThe processing of Group Policy failed because of lack of network connectivity to a domain controller. This may be a transient condition. A success message would be generated once the machine gets connected to the domain controller and Group Policy has succesfully processed. If you do not see a success message for several hours, then contact your administrator.
Event InformationAccording to Microsoft :
Cause
This event is logged when the processing of Group Policy failed because of lack of network connectivity to a domain controller.
Resolution
Correct network connectivity
To correct network connectivity:
1.Open a command prompt window on the computer, and then type ipconfig /all.
2.Make sure that the computer has an IP address in the correct IP address range and does not have an Automatic Private IP Addressing (APIPA) address (an IP address in the 169.254.x.x range).
3.Ping the loopback address of 127.0.0.1 to verify that TCP/IP is installed and correctly configured on the local computer. If the ping is unsuccessful, this may indicate a corrupt TCP/IP stack or a problem with the network adapter.
4.Test whether you can ping the local IP address. If you can ping the loopback address but not the local IP address, there may be an issue with the routing table or with the network adapter driver.
5.Ping the IP address of a domain controller in the users' and computers' domain. Failing to ping the these domain controllers indicates a potential problem with the network in between the computer and the domain controllers. Diagnose the problem further using Network troubleshooting procedures.
6.Ping the fully qualified name of a domain controller in the users' and computers' domain. Failing to ping the name of these domain controllers indicates a potential problem with name resolution between the computer and the domain controllers.
7.Follow Network troubleshooting procedures to diagnose the problem further
Note:The steps listed above may have varying results if your network constrains or blocks ICMP packets.
