I have SBS2011/Exchange 2010 and whenever I tried to stop Exchange Search Indexer service in Services.msc, it fails with "Error 1053" and status is stuck in "Stopping". So I run:
(1) sc queryex MSExchangeSearch - to obtain processor ID
(2) taskkill /f /pid 8580 - to kill the processor
Then the status changes back to "Started".
What is causing this problem? How do I fix this?
