Event viewer says:
The Microsoft Exchange Mailbox Replication service depends the following service: MicrosoftExchangeSA. This service might not be installed.
But --
- MicrosoftExchangeSA is running.
- The message persists even when I delete (in the registry) the service dependency.
This server used to be a domain controller. I finally gave up on trying to run Exchange on a domain controller (a supposedly "supported", but not recommended configuration, which is Microsoft-speak for "all sorts of things won't work right"), but the problem persists.
I've searched for solutions, and I haven't been able to find anything else about this particular error.
