Make DCPromo GUI available for demoting a DC
Before removing the ADDS role the DC needs to be demoted to a regular server. The only way to get the link to the GUI is to create an error by trying to remove the ADDS role when you KNOW you cannot do so. Trying to do so will produce the error and the error message will give you the link.
Isn't that kind of stupid? Why first make me do something wrong to get the link to do it right?
