Imagine, for an instance, that you changed all the IP’s of your Exchange Organization and now, suddenly, the following Exchange Services do not start automatically, as they should :
– Microsoft Exchange Service Host
– Microsoft Exchange Information Store
– Microsoft Exchange System Attendant
The solution for this odd problem is, in fact, very simple 🙂
To resolve this issue, browse to the Active Directory Sites and Services Console and make sure that the Exchange Subnet Ip’s are in place and are correct.
If the Exchange tries to read this and doesn’t find what he needs, he will fail and the error given is not that easy to catch.
After this step, reboot the Exchange Server and you’re good to go.
Hope this saves someone a huge amount of
