For some strange reason, we seem to have lost the "Microsoft Exchange Search Indexer" service from both our main OWA servers. We recently had a major power failure on our DC which dropped half the network. As a result, OWA users can't search and get "The actions couldn't be completed . . ."
I can't find the "msfte" msi or install on our Exchange DVD, or anywhere else reliable on the 'net.
I've also been through the restart server, try repair of Programs and Features, stop/start Microsoft Search (Exchange) etc.
The service still exists on a 3rd server which doubles as half of our DAG, but it's not a main HUB.
How can we reinstall the Exchange search service ?
