Here's the situation:
Win2k3 SBS Server running Exchange and IIS. Someone uninstalled, reinstalled IIS and now Exchange won't start. I tried to start the Information Store service and Routing Engine service, but get the following errors:
"Windows could not start the Microsoft Information Store on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service . . . [etc.]"
"Could not start the Microsoft Exchange Routing Engine service on Local Computer. Error 1083: The executable program that this service is ocnfigured to run does not implement the service."
I can post the Event Log entries if that would be helpful. I am hoping there is a fairly simple fix for this, but I don't use Exchange much, so I'm in over my head.
