Microsoft Exchange 2007 Information Store fails to start after a reboot or a cold boot. I'm running on Windows Server 2008 Standard SP2 64-bit. Exchange Version 08.03.0137.000. I followed KB article 285116. Everything seems to be ok in the registry as well as the permissions as listed in the article. The two event errors I see in the log are: Event ID 5000 - MSExchangeIS - Unable to initialize the Microsoft Exchange Information Store Service - Error 0x96f Event ID 1026 - MSExchange EdgeSync - Topology load generated transient exception Could not find any available Domain Controller.. EdgeSync must be able to acquire current Exchange topology data from the Active Directory directory service to properly operate. The Edge Transport server will attempt to load the topology again I am suspecting some DC and Group Policy problems which may need to be resolved first. Any suggestions are greatly appreciated. Thanks.

You should check in site and services to see if the subnet where exchange redise is accosiated with a site that contains writable DC. Ron

Is your exhcange is working as DC to? This issue is because of when exchange services are coming up - at the point not able to find topology. if exchange is on DC, It is expected to get these kind of warnings, and if not then please try disabling antivirus and other third party services on exchange for a test. other than than you can select option to delay start of services of exchange IS.Best Rgds, Ashish | Unified Comunication | MCTS | MCITP | Please remember to select option "Propose As Answer" if solution work for you | My posts hold no assurances, no promises, and they measured no rights.

Are you able to wait some time and then manually start the services thereafter or will the services not start at all?Troy Werelius www.Lucid8.com

I am able to wait for the server to be fully up and running and manually start the IS. For a while the IS and System Attendant wouldn't start. The SA has been starting automatically. The problem I had the other night was the the windows updates rebooted the server in the middle of the night so when I woke up the next morning I had a text from a user saying that the email server must be down. Soon as I log in and open Services I can see right away that the IS service is not running.

Sounds to me like with a timing issue OR your Ad or PDC has come issues. Have you run any health checks on your PDC and AD? http://msmvps.com/blogs/ad/archive/2008/06/03/active-directory-health-checks-for-domain-controllers.aspx For health check in Active directory DCDIAG http://technet.microsoft.com/en-us/library/cc180912.aspx http://www.microsoft.com/downloads/details.aspx?FamilyID=22205827-c164-4b62-9f8d-c3cd6077bd82&displayLang=en For health check in Exchange http://technet.microsoft.com/en-us/library/cc164306(EXCHG.65).aspx http://www.msexchange.org/tutorials/Exchange-ISINTEG-ESEUTIL.html For health check in DHCP http://technet.microsoft.com/en-us/library/cc731415(WS.10).aspx http://software.informer.com/getfree-dhcp-health-check/ Troy Werelius www.Lucid8.com

Thanks Troy, I will give those a shot. I had to work out some AD and Group Policy problems first. This is my next step as well as some DNS issues I think I'm having.

Excellent, let me know how things goTroy Werelius www.Lucid8.com
