I have come across a weird situation.
We have 3 domain controllers, 2 Server 2008 R2 & 1 Server 2008, in our single domain environment. When I login to one of the DCs, let's say DC1, with my domain admin account and access Group Policy Management Console (GPMC), I can't edit any GPOs, and also I can see inaccessible next to few GPOs applied to the domain. However, with the same domain admin, when I access GPMC on another DC, I can see all the GPOs applied to the domain and I can also edit all the GPOs.
I have also noticed that under the problematic DC,DC1, I cannot see 2 GPOs at all under the Group Policy Objects node on GPMC. Whereas, I can see them on the other two DCs.
I have done a lot of research on this, but so far no luck!
