HI in my company server, there is an error and i cant view the Active
Directory, and i cant up new users or groups. the error is....
The maximum account identifier allocated to this domain controller has been
assigned. The domain controller has failed to obtain a new identifier pool. A
possible reason for this is that the domain controller has been unable to
contact the master domain controller. Account creation on this controller
will fail until a new pool has been allocated. There may be network or
connectivity problems in the domain, or the master domain controller may be
offline or missing from the domain. Verify that the master domain controller
is running and connected to the domain.

That's saying it ran out of RIDs. It can be a number of issues causing this,
from DNS misconfiguration, disjointed namespace, single lable AD DNS domain
name, firewall rules blocking domain traffic between Sites from the RID
Master to a DC needing to replenish the RID pool, etc, etc.

To further help, we'll need more specific info, such as:

Can you post an unedited ipconfig /all of your DC(s), please?
How many DCs do you have?
Are they all in one Site?
Which one is the RID Master?
Can you also run:
dcdiag /v and post the results too?

Thanks

First, thank for you help, i have this problem 2 weeks last,
and i cant show the "Domain Control security policy" but the "local
security policy" yes, the message is "You may cant appropriate right"
and the haswers is:
1-yes in all my DC server i can make ping, and IPconfig is OK in all DCs
2-i have 2 DCs servers, i make the DCPROMO (in the backup server) for remove
the Active Directory 4 week last, but the server show the error and i reboot
the server but the active directory not show, but i copy icon (direct access
icon) active directory the Master server DC and copy this icon in the
backupserver DC, and make doble click and run the active directory in
backupserver but dont synchronizes the DCs servers, i make a proves and
disconnect the backupserver DC because i think and say me... may be the
problem is the error in backupserver DC, but not the Active Directory in
Master server is equally.
3-and all (2 DCs) servers is in one site
4-Only one is the RID Master
5- Yes i can run DCdiag /v and show mw this....

Marco,
Thanks for posting the dcdiag.

According to this section of the dcdiag:
=================
Domain Controller Diagnosis
* Active Directory LDAP Services Check
Although the Guid DNS name
(499947cf-33ec-4d0a-985e-fb91e089e675._msdcs.ids.com.mx) resolved

server
name (smprod01.ids.com.mx) resolved to the IP address
(192.168.123.201) and could be pinged. Check that the IP address
is
registered correctly with the DNS server.
......................... SMPROD01 failed test Connectivity
=================

It looks like the DC has two network cards. Is this true? That can be the
cause of the whole problem. Using the wrong DNS addresses in IP properties
can also be the cause. I'll need more information please. I was looking for
the ipconfig /all, but couldn't find it in your post. That will be very
helpful.

Can you post an ipconfig /all from both DCs please?

Thanks

Ace
 
Thank Ace Fekay, in your las message you tell me about the IPs ands i change
the IP the DNS in the networkcard and all OK!! really thank you save my life!
only one comment for all user, when i change the IP networkcard my exchange

inmediatly.
