I have a COM+ application made up of 3 components. In the Component Services UI on the Win2003 server, I can right-click and disable any Component. Then I can right-click and enable it again. I can do the same when an Appliation is enabled or disabled. I want to do something when an enable or disable occurs, whether programmatically or through the MMC Component Services UI. I want to take action in my C# code when a component or application is enabled or disabled. I have code that already covers the startup and shutdown sequences. Thanks.
