At one point, while working with Microsoft Data Protection Manager I came across the following humorous quote – unfortunately I don’t have the source. Enjoy!
“When asked how to find out who owns an application running on some physical or virtual server, or to know whether anyone is using the server, the simple answer is to just unplug the server from the network or pause the virtual guest session. If someone is using the application, you will hear from that person pretty quickly. There are obviously more elegant ways to identify application ownership and usage monitoring access to the system, even by sending a message out to query the organization if anyone knows who is administering, managing, or using an application. However, there comes a point where the disconnect/pause message returns a much faster approach.”
