secondary domain controller error

dear gurus

our master server is alive and working fine but when we try another server additional domain controller so it give below message

v r using w2k8 r2

you will not be able to install a writable replica domain controller at this time because the RID master master0.domain.com is offline

any one can guide step by step

it seems the RID role holder is down or decommissioned
run dcdiag /test:fsmocheck and seize the roles which are in error
I would suggest to go through below link and seize the roles to working DC

Seize FSMO role:

After seizing roles run dcdiag /q and post any errors

I think it is a DNS misconfiguration, before we proceed any further jus let us know howmany DCs are there in the domain. Is it 2 including problem DC or more?

Based on your answer we can say what needs to be done. However I would suggest you to check some settings on Main DC (Alive one). Check DNS and Time Server settings first and fix them if you see any misconfigurations. Then Rund DCDiag /v to know AD health status. If everything is fine then you can fix the problem DC.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Logon to master0.domain.com  and see the event logs. Maybe the server got culled sometime.

As mentioned it is a DNS misconfiguration issue. "The replication generated an error (1722)" is an indication of GUIDs are not getting resolved between DCs, I would again suggest you to check dcdiag /test:dns on all DCs and if it fails resolve it accordingly. I see replication between ATMCSRVR17, ATMCSRVR12 to ATMCSRVR10 is failing. If you run repadmin /replsum and repadmin /showreps you'll see more detailed errors.

From the log it is clear that there is replication issue between DC.You are getting RPC service is unavaialble,Insufficient attributes were given to create an object. This object
may not exist because it may have been deleted and already garbage collected whcih indicates presence of lingering object issue.

 "The RPC server is unavailable" relates to port being blocked or network connectivity issue or due to dns misconfig.I would suggest contact network/security team to verify whether all the related AD ports being configured and allowed on the firewall for communication. Portquery is free tool from the MS which can be downloaded and installed to verify the necessary ports are opened or not.

Also, disable local windows firewall service, by default it is enabled in vista/windows 2008 and above. Check the network connectivity and latency.

It can also be caused by antivirus software with many of them sporting a new feature called "network traffic protection," which can efffectively block necessary AD traffic

Troubleshooting “RPC server is unavailable” error, reported in failing AD replication scenario.

For lingering object see this:http://blogs.technet.com/b/glennl/archive/2007/07/26/clean-that-active-directory-forest-of-lingering-objects.aspx.

If you have multiple DC in the network you can demote & re-promote the DC containing lingering object.Sometimes its difficult to remove lingering object either using repadmin /removelingeringobjects or other tool & easiest way to deal with such issues is demote & re-promote the DC. If lingering objects spreads int the domain then its more difficult to tackle them. Demote & promote is the best solution.

If there are instances of faulty DC which is removed from network and instances are present in AD then you need to run metadata cleanup.
