I just updated my SQL Server Service Manager application. It's designed to manage services that are part of SQL Server 2000 & 2005. It has support for multiple instances on the same machine and allows creation of saved sets of services for quick control. Can be useful to bulk start/stop SQL (when you need memory) or for switching between multiple instances. The newest version adds support for "Pinning Down" services so that the current set is the start-up one. I also updated the UI to look better on Vista (minor sizing).
Version 1.0.0.10 is available as ClickOnce here.
ENJOY.
