Failed to open the group policy object

Can you please look in Event Viewer & post the errors you getting in there?
A

Below is the error message
The processing of Group Policy failed. Windows attempted to read the file \\ISecureD.com\sysvol\ISecureD.com\Policies\{31B2F340-016D-11D2-945F-00C04FB984F9}\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following:
a) Name Resolution/Network Connectivity to the current domain controller.
b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller).
c) The Distributed File System (DFS) client has been disabled.

Do you have more than one Domain Controller?
It seems to be the Replication issue see this: File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller).

Also, can you please post the Event ID?
A

Also I have noticed that when I tried to access the sysvol file using \\servername. the folder is inaccessible.
thank you

There you go, if sysvol replication is not working nothing is gonna work for Group Policy.
Can you describe your infrastructure?
Also please post the Ipconfig /all from your server.

A

There is only one domain controller, the eventID is 1058

I also tried creating a new folder then sharing it and I realise that folder cannot be access by \\servername\foldername.

Can you ping server with FQDN?
A

Yes it is replying with an IPV6 address.

Funny IPv6 is not checked but it still response with IPv6 IP. Any idea?
