Dear all I've added a 2 new windows 2008 domain controller in 2003 forest, but my Exchange 2007 do not list them his available DC and GC. No error in DCDIAG test.Thanks

Hi,~ Have you rebooted the servers after replication is fully completed? Try with that...~ Windows 2008 RODC/ROGC is not supported with Exchange 2007.~ Can you post event it 2080 which logged on Exchange server to here to find out cause?http://support.microsoft.com/kb/316300Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

This is event 2150 as you can see the new ones are not presentProcess MSExchangeMailboxAssistants.exe (PID=260). The following Active Directory servers are going to be used in connection pools of this process: Domain Controllers: eidos02dc.EIDOSMEDIA.COMepress01dc.epress.itepress02dc.epress.italeph01dc.alephinfo.iteidos01dc.EIDOSMEDIA.COMaleph02dc.alephinfo.itGlobal Catalogs: eidos02dc.EIDOSMEDIA.COMaleph01dc.alephinfo.iteidos01dc.EIDOSMEDIA.COMaleph02dc.alephinfo.itepress01dc.epress.itConfiguration Domain Controller: epress02dc.epress.it. Topology Version 92, Topology provider: DSAccessTopologyProvider.

It seems that new DCs/GCs are being detected. Basically DC/GC lookups used by System Attendant (mad.exe) and Information Store (store.exe) services and information provided byActive Directory Topology Service (MSExchangeADTopologyService.exe)so you need to verify 2080 event for these processes.However you can check in System Settings tab of server properties or by running Get-ExchangeServer -Status cmdlet to confirm that DC/GC are being used for AD info lookups.Server Properties > System Settings Tabhttp://technet.microsoft.com/en-us/library/bb629520.aspxAbout event id 2150, it is forMSExchangeMailboxAssistants.exe process which performs background processing of mailboxes in the Exchange store and not for normal categorizerlookups. I guess it starts detecting after restartingMicrosoft Exchange Mailbox Assistants service or Exchange server.Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

My problem is that new dc's are not listed inSystem Settings Tab. Thank you anyway......

Hummm, it seems that SCL Right flag shows 0 and which is creating problem. Check out second response in below thread for identical problem andgivenTSecurityDescriptorRead permission on OU, where these DCs are located, to Exchange Server security group...http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/4cfab637-4d82-4c03-9362-5fa11777c70d/Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

Hi, 1. Please ensure that IPV6 has been enabled on Windows Server 2008. 2. Please ensure that Exchange Servers has been listed under Local Security Settings for Manage Audit and Security Logs. Note: You can run secpol.msc from a command prompt to open local security settings-Local Policies-User Rigths Assignment-Manage Audit and Security Logs. 3. Since these two DCs are newly installed, then please run Setup.com /preparead and Setup.com/ Prearedomain. For more detail information on Event 2080,you can check article below: Event ID 2080 from MSExchangeDSAccess http://support.microsoft.com/default.aspx?scid=kb;en-us;316300 Regards, Xiu
