Should Clustered services be set to 'manual' or 'automatic'?
The question goes something like this:
My cluster is installed and running SQL/Exchange nicely but I noticed that all the services for SQL/Exchange are set to start manaully. Should I set the services to automatic instead?
Answer:
Cluster controlled services should always be set to manual, so that the
cluster can control the startup and shutdown. Remember with Microsoft
clustering only one server can control a resource at any given time. Leaving
the services set to manual will help the cluster service do it's job and
ensure an error free service :)
