Access Denied to policy editor
I have windows 2003 ENT. server installed with AD running on.
When i try to open "Domain Controller Security policy" link, or "Domain Security policy" link from administrative tools or even from system32 folder, i get the error --"Failed to open the Group Policy Object. You may not have apporpriate rights." And in under details : "The network path was not found"

Here is the screenshot of the error

I even tried a step stated on microsoft's website

After this step this is the error that's coming

But no resolution.

What should be done ?
