As far as why they aren't included in Windows anymore, I would say because of the infamous "Decline of Novell". To be honest, I haven't seen Novell being used much.
I guess I was wee lad when it was in it's hay-day.
After installing the client services, reboot your computer, and check your services to make sure the service is running and installed in the connection properties . If you have anymore problems let me know and I'll do what I can to help.
