This server is neither the operations master, nor the DNS server, nor the DHCP server. I presume that the Active directory was not installed correctly on this server coz when I try to open AD from administrative tools it shows the following error message: “Naming Information can not be located for the following reason: The server is not operational. “ So I am trying to demote this server from being a DC. But, when I run dcpromo to demote this server, it shows me the following error message: “The operation failed because: Managing the network session with anotherdomaincontrollername.domainname failed. A device attached to the system is not working” I am very new to Active Directory. So, could you kindly suggest me on what I should do? – Ashok Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
