VS.NET2003 error, prompt "Visual Stadio.Net is not ASP.NET1.1 version of the web server", check the settings of IIS5.0, found that there is no ASP.NET filter. Because it is good, it is speculated that the problem that may reload the IIS server, so the first reaction is to reload the ASP.NET through the VS.NET installation disk, but the fault is still still. Check the information on the Internet, use the ASPNET_REGIIS.EXE -I command, troubleshooting.
