Is this article a joke! I don't have time for jokes!!!

Well, you could erase the hard drive and reinstall. What do you have on hand? Snow Leopard? Lion on a USB stick?

Not sure what you mean. that article explains is very well. Lion server is just an App. It not really another OS.

Just delete what it tells you to and it will be gone.

The app installs several thousand files all over the system. There's no uninstaller.

It does seem a little counter intuitive that opening Server.app for the first time requests if you would llike to configure the local machine as a server and the only real options are besically "Yes" or "No" It would be great if there was another option for "Connect to a remote server" that WASN'T burried in the file menu and by a confusing dialogue box. The first time I saw this I said " Yeah! Of course I want to configure Server." and ended up installing (or rather enabling) the services on my MacBook Air. I know many people remotly administer OS X servers and with the oddball way of obtaining Apple's primary tool for server administration (drag and drop it from a copy of OS X Server) it would be great if they could give more information in that priliminary dialogue.

Either way, most of OS X Server's services are already installed and many are even running, the Server.app tool just enables a level of control over those services. So as the article suggests, disabling them is the easiet way to "uninstall" or rather disable what was already there.
