Difficulties creating a dial-up connection

Hi all,
I own an Inspiron 4150.I have recently reinstall my OS(WINDOWS XP HOME), and I have reinstalled all the drivers and updated my BIOS system. However, I cannot create an internet connection using dial-up, below are the errors I received while trying to create a new connection using different methods:

1)When I use Control Panel->Network and Internet Connections->Network Connections->Create a new connection, I have the New Connection Wizard, but I cannot select "Connect Using a dial-up modem".

2)When I use Explorer->Tools->Internet Options->Connections-> "Add", this message appears "Cannot load Remote Access Connection Manager. Error 711: A configuration error onthis computer is preventing this connection. For further assistance, click more info or search Help & Support Center for this error number."

Then I proceed on to start the Remote Access Connection Manager under Services, but I receive this message "Cannot start Remote Acess Connection Manager on Local Computer. Error 5: Access Denied"

3)I've checked the properties of my modem, it is attached to COM 5. But under Device Manager-> Ports, I have only a Communication Port COM1. Will this pose a problem?


P.S : The modem have passed all tests under Dell Modem Help, it is an internal modem already installed in my computer when I receive it(Actiontec MD56ORD V92 MDC Modem)

Thank you for your kind help!
