YOUR PREVIOUS ANSWER:
As of V1.0, there's a command-line utility to re-configure ASP.NET with all Web sites on your machine. You have to run the following command at the prompt:
Replace path with your current windows folder and .NET version. (The one I used is for v1.0.) That should do the trick.
Like I said in my answer, you have to replace the path with the appropriate one for v1.1 on your machine. And if you're using Win2k, the first folder is going to be WINNT and not WINDOWS: c:\WINNT\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe /i >[?There may have been an error while editing the content that caused the backslashes to be lost or misplaced (such as the //i).
You also need to have FrontPage Server Extensions installed and enabled in IIS to create a new Web application from VS.NET.
Another cause for the error is probably due to IE having a proxy configured. If FrontPage access is used to connect to the site, VS.NET may try to connect through the proxy, which will fail, of course. A reader reported that even if 'bypass for local addresses' is specified, VS.NET will ignore it.
