I'm running windows 2000 on a dual boot system with windows ME. I am having problems connecting to my isp with w- 2000. Windows ME connects fine. In windows 2000 I get a PPP error 720 and I cannot connect to my isp. I have tried un-installing/re--installing tcp/ip, network adaptor, modem, etc. I also made new LAN and DUN connections. I have even uninstalled Norton anti-virus. I have noticed that every time I reinstall tcp/ip a "Wan miniport adapter #2" appears in my device manager under network adapters. I cannot uninstall it there because says it is required to boot my computer but when I uninstall my 3 com network adapter and uninstall my tcp/ip the wan miniprt adapter disappears also . I have a feeling that this has something to do with my problem. Can anyone help?

I've already been there. Unfortunately, Microsoft doen't have the answer. I removed my network adapter and am no longer on the network. Now when I install TCP/IP I get a wan miniport network adapter even though I no longer have a network card. If I uninstaqll Tcp/ip the wan miniport adaptter goes away. I have spent countless hours trying to figure this out. Unless someone has any better ideas, I think its time to back it up and "flush the toilet" on this one and go for a clean install. Thanks, Larry

It seems W2K doesn't like uninstalling and then re-installing any of the network components like TCP/IP. On my W2K computer, I have never played with those network components and it still connects perfectly. Conclusion: MS should warn the users about it more clearly, i.e. "Do not uninstall and re-install TCP/IP, or you may have to (clean) install W2K again to keep using that feature". Just my idea.
