Domain Controller replication issues

Hi Guys,

Have an issue with domain replication and DNS.

I have 2 DC's. DC1 and DC2.

On DC1;

Hold FSMO roles

Opening DNS gives me, "Access Denied"

Event Log error;
ID 2092 - ActiveDirectory_DomainService
ID 1202 - ADWS
ID 1055 - GroupPolicy
On DC2;

in AD sites and services when i right click on NTDS Settings on either DC1 or DC2 i have DNS Alias as something random : A439058ASD0F98W4095ASD09.DOMAIN.INTERNAL. not sure if thats right or not.

in AD users and computers when i right click on domain and Operations Masters, the RID and PDC and Infrastructure Operation Master says, "ERROR"

in DNS when i right click on the internal domain zone and properties then Name Servers, i edit DC1 and the IPV4 reports, "The server with this IP address is not authoritative for the required zone, BUT the IPV6 address says, OK.

Event log errors;
ID 4 - Security-Kerbros
ID 1864 - ActiveDirectory_DomainService
ID 2093 - ActiveDirectory_DomainService
ID 5773 - NETLOGON


both servers are 2008 and functional level of domain is 2008.

please help

Hi,

Does event ID 2092 state the server considers the FSMO rules invalid?

TimbobalobaAuthor Commented:
correct. i have;
Log Name:      Directory Service
Source:        Microsoft-Windows-ActiveDirectory_DomainService
Date:          13/12/2013 10:50:34 PM
Event ID:      2092
Task Category: Replication
Level:         Warning
Keywords:      Classic
User:          ANONYMOUS LOGON
Computer:      ccs1.internal.ccsale.catholic.edu.au
Description:

This server is the owner of the following FSMO role, but does not consider it valid. For the partition which contains the FSMO, this server has not replicated successfully with any of its partners since this server has been restarted. Replication errors are preventing validation of this role.
 
Operations which require contacting a FSMO operation master will fail until this condition is corrected.
 
FSMO Role: DC=internal,DC=local

Hi again,

You could try to transfer the FSMO roles to another server.
Some fixes are discussed here.

that makes sense. i will attempt to sieze roles from itself now and report back.

MaheshArchitectCommented:
have you logged on with ID having domain admins right ?

Alias you seen in AD sites\Ntds settings are correct.
Just copy those alias for all domain controllers and check if you are able to ping them successfully.Every aliase should resolve to actual domain controller IP address, if not you can restart netlogon service on both domain controllers to correct those alias entries.

Also IPv6 need to be unchecked from network card properties of both DCs

What if you run repadmin /showrepl, can you please post output here

Yes, I am logged on as administrator (domain admin)

from DC2 (primary DNS) i can ping ntds alis of both DC1 and DC2
from DC1 i CANNOT ping DC1 alias but CAN ping DC2

IPV6 IS disabled on both DC.... wierd....

Can you restart netlogon service on DC1 and check if alias is regenerated ?

If not , then please create it manually and also ensute that you have Host(A) and PTR records of both DCs on both server exists
