SPServerRole always returning "Application" (SharePoint 2010)

Hello,

We are trying setup 3 tier architecture for SharePoint 2010. We are configuring a Machine to be a WFE. After reading various blogs, we have kept only 4 services running on that Server.

a) Central Administration

b) Microsoft SharePoint Foundation Web Application

c) Search Query and Site Settings Service

d) SharePoint Server Search

There servies are not running on another machine, which is an Application Server

But whenever we try to get Server role for 1st server, we are getting it as "Server".

What needs to be done to make it WFE???
