Why can’t I remove the Component Server Site System Role in SCCM 2012?

Why can’t I remove the Component Server Site System Role in SCCM 2012?

I am trying to remove a ConfigMgr 2012 Distribution Point (DP) from a server. I’ve gone to Administration | Overview | Site Configuration | Servers and Site System Roles

I right-click on the server that is hosting the DP I want to remove and select Delete from the context menu.

However, I then get a Delete Server dialog box stating:

The server "'\\<server_fqdn>" cannot be deleted because it contains the following site system roles:

Component server

The component server role supports other site system roles and is created automatically by Configuration Manager. Although there might be a delay, this role is automatically removed after you remove other site system roles on this server.

I’ve tried right-clicking on the Component server role under Site System Roles but the Remove Role option is greyed out so I’m unable to remove the Component Server Site System Role.

As this server is only hosting a DP I don’t understand why it has the Component server installed on it.
