I am facing a problem on the RODC servers located on remote locations from the main office which affects both DNS and DHCP. When this services are down the critical business serices goes down including even file services. The background of this problem is brought about by WAN network connection outage. We have come across different logs which have been discussed onn various forums here: 4000. 4015, 4013...and many more on DNS and also error log on DHCP: The DHCP service failed to see a directory server for authorization. What I am looking for is not how to restore DNS service back or authorize DHCP because for sure when the WAN network is back, when I point to main DC and reboot, then force replication all this services are restored back.
What I need is for example for DHCP found that we can disable rogue detection:
To disable rogue detection
- Click Start, type regedit in Start Search, click Yes in User Account Control if prompted, and then press ENTER.
- In the registry tree, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\DHCPServer\Parameters.
- Right-click DisableRogueDetection and then click Modify…
- In Value Data type 1 and then click OK.
and the DHCP service will not stop working.I have not found a solution for DNS though some post have pointed to setting the registry valueRepl Perform Initial Synchronizations to 0 in order to bypass initial synchronization requirements in Active Directory as per http://support.microsoft.com/kb/2001093.
IS there any solution or configuration with evidence which will amke sure that this services can remain working when connection is down, please all your support will be helpful. I know there are good minds and quick here....
