***Calling all SMS experts***

I am trying to install the SMS client software via SMSMAN from the SMSlogon share on the PDC. When I install it, I get the following message at the end of it “The Systems Management Installation Wizard completed successfully but no Systems Management sites were configured to manage you computer.” The clients that I am trying have been previously installed and worked fine and they fall in the IP boundry range. I only have 1 site. Help!
