Question : linux Centos server

I have installed Linux Centos 5 , i don't remember being prompted to select  between a server or a workstation.
Now how can I tell if it's a server or a workstation, and how to revert it a server if it's a workstation.

I also have tried the command ifconfig and it didn't give anything, what should be wrong?

thanks

Check this:

<cfhttp url="http://api.twitter.com/1/trends/current.json"></cfhttp>
<cfset current = deserializeJSON(cfhttp.FileContent)>
<cfset trendsName=StructKeyArray(current.trends) >
<cfset trends=current.trends[trendsName[1]] >


<cfoutput>
    <cfloop from="1" to="#arrayLen(trends)#" index="i">
          <a href="" class="bold">#trends[i].name#</a><br />
    </cfloop>
</cfoutput>
