sms 2003

i have installed sms 2003 in windows 2003 enterprise server, and was trying to collect the hardware and software inventory.I had dwnloaded some pdf files ,wherein they had mentioned the step by step procedures.

While configuring a management point ,it was mentioned that that the sms host agent service will be installed ,but when i checked the services panel ,it was not installed.

I can see my windows 2000 proff system in the collections tab and i tried installing the advanced client software from there ,but it didn't install .Hence, i installed the client.msi file manually on the client ,but still i cannot observe the client installed as an Advanced client ,in the sms console .

where am i going wrong.

kindly help
