Troubleshooting:(Windows sever 2008) DHCP server Access Denied

Lets say you added a new role in your Windows Server 2008 a DHCP server.
Now you trying to authorize it so it can accept DHCP clients request but you are getting a Access Denied message






This happens when you do not have permissions to do this
you NEED to add the user you using to a group which have permission to do it i mean to authorize your DHCP server to distribute DHCP to DHCP clients

You could add it to some default groups such like domain admin

After you ADD this user to the group which have permission to do this you NEED to log off that user and then log in again.
