Hi All, I have the problem that the OAB is not genarating the Address Book. It looks like a security issue, because the machine is on, and reachable. Some info: The servers prc19n01 and prc19n51 are the domain controllers from the root domain. Exchange 2007 SP1 - rollup 9 Generation server is one (of 2) HUB/CAS/MBX (only public folders) servers. 3 Mailbox CCR's We get the following errors (information) in the eventlog Eventid: 2090 Process MSEXCHANGEADTOPOLOGYSERVICE.EXE (PID=2016). Exchange Active Directory Provider has discovered the following servers with the following characteristics: (Server name | Roles | Enabled | Reachability | Synchronized | GC capable | PDC | SACL right | Critical Data | Netlogon | OS Version) In-site: prc19n01.root.xx CDG 0 0 0 1 0 0 0 0 0 prc19n02.directory.xx CDG 1 7 7 1 0 1 1 7 1 prc19n51.root.xx CDG 0 0 0 1 0 0 0 0 0 prc19n52.directory.xx CDG 1 7 7 1 0 1 1 7 1 prc19n53.directory.xx CDG 1 7 7 1 0 1 1 7 1 prc19n03.directory.xx CDG 1 7 7 1 0 1 1 7 1 Out-of-site: For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

If have been searching, and found a couple of articles, but non of them seems to apply here, in a root/child configuration.

Hi , Please try these steps I hope it will resolve your problem. 1. Stop and Start the DNS Server Services on the GC and The DC machines. 2. On the Exchange Server, where does the DNS entry point to ? Change the Primary to point to an AD integrated DNS or another GC in your organization within the same IP Site. 3.Set all Exchange services to stop and manual. 4.Open - Properties, DSACCESS, and uncheck the Automatic checkbox 5.Add the DC and The GC's Manually 6.apply and restart the server 7.ipconfig/flushdns and ipconfig/registerdns 8.before you start the Exchange services, on the GC's click on DNS Server properties and choose clear cache 9. Nslookup yourdomain.com should point to all IPaddresses of your GC's n DC's. 10. On Exchange Server start the DNSClient and DHCPClient service, Server Service. 11. Start exchange services manually 12. Flush the cache by typing this on the command prompt Net Stop Resvc Net Stop SMTPSvc Net Start SMTPSvc Net Start Resvc The logs must be clear of this errors now...! Regards. Shafaquat Ali.

Hi , Please try these steps I hope it will resolve your problem. 1. Stop and Start the DNS Server Services on the GC and The DC machines. 2. On the Exchange Server, where does the DNS entry point to ? Change the Primary to point to an AD integrated DNS or another GC in your organization within the same IP Site. * It is already pointing to a DC / GC in the same site (prc19n52) 3.Set all Exchange services to stop and manual. 4.Open - Properties, DSACCESS, and uncheck the Automatic checkbox * Here i'm lost, what to open?

@ Christina, I have seen this article, but I didn't apply to fix. I have read it, in de understanding that the fix only applies when the CCR is creating the OAB. In our situation the OAB is genarated by a HUB/CAS server which is not part of the CCR.

Hi fvanloon, Did you view this article to troubleshoot it: http://blogs.msdn.com/b/dgoldman/archive/2007/11/15/oab-generation-fails-to-generate-with-errors-9330-and-9334.aspx Please check it and confirm whether can help you. Thanks Allen

I'll look in to it today. Been away for some days..sorry for the late response.

Hi, Thanks for your update. Please try and post here if you have questions. Thanks Allen

Problem is resolved, thanks to PSS The root domain controllers couldn't be resolved based on the NETBIOS name. We tried pinging them on IP-address and on the FQDN. We added the DNS Suffix , and the machine could then be reached by the OAB process.

Hi Fvanloon, Thanks for your sharing. How did you know the DC is the issue? If possile, could you share more information here? John

Hi John, The DC was not the problem, only the reachability of the DC was a problem. When we tried to ping the machine on a NETBIOS name, i could't be reached. After adding the DNS suffix on the OAB generation server, the machine was reachable, and the OAB process was running fine.

Hi, Thank you for sharing. That is indeed very helpful for the users. Allen
