To work with resources in Lotus Notes you have to create a Resource Reservation database using the template that ships with IBM Lotus Domino.
You have to edit the ACL of the database to make sure you have the role "[CreateResource]" assigned to yourself.
On the "Advanced-Tab" of the ACL enter the current server as "Administration Server" for this database and select "Modify all Names fields" as action.*
Open the database with the Domino Designer and enable all agents.
After restarting your Notes Client you can create sites and resources in the Resource Reservation database. The new resources will be added to the Domino Directory by AdminP - do not try to create the resource manually in your servers names.nsf!
