RID pool problem

[Rachid Berrada]

Hello,

I'm dealing with a problem concerning RID pool :
I have a domain with 2 DCs. After I had restored one DC (it's the
other who is the RID master), many problems appeared : First, the
replication wasn't possible until I used the netdom command to reset
the machine account. But the problem now is that the restored DC is
using an old RID pool. Here the Dcdiag result :

Starting test: RidManager
* Available RID Pool for the Domain is 8103 to 1073741823
* DC1 is the RID Master
* DsBind with RID Master was successful
* rIDAllocationPool is 7603 to 8102
* rIDNextRID: 4653
* rIDPreviousAllocationPool is 4603 to 5102
......................... DC2 passed test RidManager

Because of this, If I create a new object in DC2 tow objects are
automatically deleated (the new one and an old one that has the same
SID) and I have tow SAM event 12293 saying all the objects having the
same SID are deleated.

I think I need a command or a tool that enables me to force the DC2 to
request for a new RID pool.

Thanks for help.

Since you have another domain controller, the quickest way to get this
corrected would be to run DCPROMO on the rebuilt machine to demote it and
the run DCPROMO again to promote it back to a domain controller. This
should force a new RID pool to be assigned to it.

I forgot to tell you that this server is also an Exchange Server, so I
don't want to demote it. Is it possible to modify this RID pool using
ADSI tool or netdom command, if so how?

Thanks.

Demote and promote the DC that is having the Rid problem.
