How to Remove a SharePoint WFE/Application server from an existing farm?

You can find two methods in TechNet or other blogs to remove a SharePoint 2007/2010/2013 server from an existing farm. These methods are through central admin (Remove Server in servers in farm) and through control panel (uninstall SharePoint binaries).

I will suggest, if anybody is ever planning on Uninstalling/Removing a server from a SharePoint Farm, do not go to “Servers in farm” and click “Remove Server” or directly uninstall SharePoint on the server through Control Panel. This will cause failures in timer job status and will cause some problems down the road.

The best approach to uninstall or Remove a server is as follows

1. Log on to the server you want to remove or uninstall from the farm
2. Run the SharePoint Products Configuration Wizard
3. Select “Disconnect from Farm” and click on next
4. Click OK to continue the wizard

The wizard will take you through the steps and you should be see the “Successful Message”

Now you can uninstall SharePoint binaries from the server disconnected from the Farm.
