Problem:

I am trying to remove a 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.

Resolution:

The server in question must have had another Site System role installed on it at some point in the past as the Component server role gets installed on a server whenever a Site System role is installed with the exception of a DP (so if the server has only ever run as a DP you will not see the Component server).

Chances are a role other than the DP was installed at some point in the past and removed but the Component server role hasn’t been removed for some reason.

The quickest way to kickstart this is on the affected server:

Right-click Site system under Site system Roles and select Properties from the context menu.

Make a change to a setting on the Site system properties screen such as checking the Require the site server to initiate connections to this site system then click OK.

Wait 10 – 15 minutes.

Refresh the console and the Component server role should now have disappeared.

You should now be able to delete the server hosting the DP.
