So, you're trying to hit a site on IIS on your local machine. Is this a straight browser hit (i.e. HTTP/port80) or something else? If something else, can you connect over plain HTTP?

- I've never seen "Virtual Machine Network Services" before. Is this something that comes with VMWare or equivalent? Are you running multiple VMs with multiple OSs simultaneously, sharing the hardware?

- I'd simplify as much as possible. Remove unneeded protocols, or at least bind protocols only to those adapters where you need them. e.g. do you actually need/use IPv6? Are they all SP2-compatible? Might they need updates?

- I haven't used or encountered NetBEUI in years. You can pretty much use TCP/IP everywhere as long as you enable NetBIOS over TCP/IP.

- If you have multiple adapters in your machine, is it possible you have to tell IIS to listen on one or all of them?

- With multiple protocols bound to multiple adapters, only one can be the "default" protocol. You could experiment with changing the default protocol (especially to a different card). For sure, you'd want your default protocol to be one of the TCP/IP links, not NetBEUI.

Beyond that ... you'll need to speak with the maniac who set up your machine in the first place ;-) It's really hard trying to diagnose something like this remotely and asynchronously.

If you're using a notebook your OS is probably OEM so you can't call MS for help. Even if you could, you'd be looking at a Server support call because of the IIS and "extreme networking" involvement. Other than that, there are probably newsgroups or other hardcore network support sites where you might find help.
