Information Store Service missing

Hi Experts, something odd happened to my server and the Exchange Information Store service is missing, I check regedit and the entire key MSExchangeIS (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS) is missing. The store.exe file is still there and the physical files look to be intact.

As a result all email services are down and the database status is "Dismounted" I have access to Exhange Shell and the Management Console

Is there a way I can reinstate/reinstall the service? I am running Small Business 2011

If you have no system state backup you can restore then you could try repairing the Exchange roles as per the following technet article:


I would strongly recommend a full server backup prior to this to be on the safe side and you may need to do it at a time when nobody is using the server (I suspect it'll need some reboots).

Hi Andy, looking at the instructions I will need the SBS discs at some point but I can't find them either. Can I restore the registry files from shadow copies?
Andy MIT Systems ManagerCommented:
It should be possible but never actually recovered a registry from shadow copies myself so couldn't advise on how it would be done.

Either way, ensure you have a full server backup first, that way if the server doesn't boot correctly after the regisry recovery you can restore it to how it currently is at least.

It would be worth trying to get some SBS discs beforehand in case that doesn't work or cause more issues (if you can't locate them you'll need to purchase some additional ones or speak to Microsoft - if you have the license key they may be able to source you some).
