Office 2003 and RMS

Hello. I am new in RMS and I have one question.
I have installed on a Windows Server 2003 a RMS Server with SP2. On
the server machine I also have an Active Directory.
On my machine, I have installed the RMS Client with  SP2 and when I
want to set some permisions on some Word document, I go to File->
Permission-> Restrict permissions as... and I get a Service Sign-up
window that is telling me if I want to use the Microsoft Service trial
using .NET Passaport. Well, I don't want to use .NET Passaport, and as
far as I read on a web site, I can use certificates that were issued
by the RMS Server. I've installed a Certificate Authority on the
Server and I requested a certificate.
Now, I want to link my machine(or Office applications) to RMS Server.
How can I do that?

I figure it out... I had to activate the client...
and now I have :
