the following protocols installed (via your dial up networking connection properties) before the service will work:
Internet protocol (TCP/IP)
QoS packet scheduler
Client for Microsoft networks
The type of server you are calling should be set for: PPP:Windows 95/98/NT4/2000 Internet.
In the Windows add/remove components networking section you should only need to add the Internet Gateway device discovery component - the other three boxes needn't be ticked, and if you've been told they should I am very surprised.
I've been surprised before mind you, but this time I am VERY surprised.
