ADS ERROR - The directory service has exhausted the pool of relative identifiers

It's hard to give you a step-by-step with so little info, but check if this KB is valid in your case:

also make sure your RID master FSMO is online and on a working DC.

Hi eecnmsuresh,,
Its seems to be a problem of RID master. See the steps below to resolve the issue.
pls test it firts in your lab
eecnmsuresh: warning (its so critical so dont try it in your live DC, test it first)

1.Move the computer that you want to restore to a separate network that is isolated from your production network.
 
2.Restore this computer from backup. Do not restart the computer when the restoration is complete.

3.On the temporary RID Master domain controller on the production network, open a command prompt, type repadmin /showvector, and then press ENTER.

4.Shut down the temporary RID Master domain controller, and then move it to the separate network with the restored computer.

5.Start both computers.

6.Use the Sites and Services Manager Snap-in to initiate replication between the two computers. To do so, follow these steps:

a. Click Start, point to Programs, point to Administrative Tools, and then click Active Directory Sites and Services.
b.Expand the Sites container in the left pane, and then expand the container that represents the name of the site containing the target server that you must synchronize with its replication partners.
c.Expand the Servers container, and then expand the target server to display the NTDS Settings object (an object that represents the settings for the domain controller).
d.Click the NTDS Settings object. The connection objects in the right pane represent the target server's direct replication partners.
e.Right-click a connection object in the right pane, and then click Replicate Now.Windows 2000 initiates replication of any changes from the source server (the server represented by the connection object) to the target server for all the directory partitions that the target server is configured to replicate from the source server.
7.Transfer all the operations master roles back to the original role-holder.
8.Move both computers back to the production network.

Is the CNAME for Arrow4 missing in the _msdcs folder?

If yes try to:

ipconfig /flushdns
ipconfig /registerdns

and restart the netlogon service. See id the CNAME gets registered.

promote this server as Global Catalog
and then restart the server

Hi,

I tried both flush dns and promoting as global catalog server but problem persists.
 
Attached is the file status after promoting arrow4 as global catalog server.

Thanks
