We have Two domain controllers.One is PDC and second one member server.last night we restarted PDC. After restart , all servers are giving access is denied when remotely accessible by any user. now we have run gpupdate command through local administrator login into the servers. Now users can login.
But the big issue is what, that what we changes in PDC , not replicate with master server.I m not sure that this is a BDC or master server. Concept is not so cleared.
Now just make sure , i ran ntdsutil command on master server. There are some roles found.But on PDC , it is saying access is denied after ran this command.
Note: Now i facing user's password reset, computer trust relationship issues. So i removed and reinsert those computers in domain again.Problem solved.
But still i need ur help experts.
