Having an issue with authentication on my network. Running Windows Server 2008 R2
Network is a non internet connected network using DCs running DNS/AD/File Sharing. NO DHCP all addresses are Static. DNS is pointing to DC1 & DC2.
File sharing is working as if you do a \DC to it will show shares as well as shares on the rest of the network.
Problem When connected to the network machines say "unidentified network" not the domain. Secondly when I try to add machines to the domain it says it cannot reach the domain. Also users cannot login to it as it says no login servers exist.
Ran a DCDIAG on the DC1 itself and got
Got error while checking LDAP and RPC connectivity
All ports for LDAP and RPC are allowed and the firewall is off.
While running DCDIAG /TEST:DC I got this.
NO LDAP CONNECTIVITY Warning Adpapter Invalid DNS Server No host records (A) or (AAA) were found on this DC NO DNS RPC connectivity PTR Record query for the *** failed on the DNS Server Name resolution is not functional
I have been working on this all week and it is driving me crazy. Do I need to backup my entire A/D and redo it or am I missing something I don't understand here. I can't add machines to the domain and network accounts will not login and all machines say they are on an "unidentified network".
At this point I have only the DC on and 1 computer. The DC says it is connected to the Domain but the computer say it isn't. I can Remote to the DC by name. Not sure what to do at this point.
UPDATE:1 After adding a system account and service account to the security groups for file replication and one for certificate access which allows the machines to see the domain. CURRENTLY STILL GETTING LDAP and RPC connectivity issue which is preventing the machines from joining the domain. Login servers seem to be working atm but still cannot add machines to the domain. Is there a way to rebuild or reconnect LDAP?
