After you install Internet Protocol version 6 (IPv6) on a
computer running Windows XP, Visual Studio .NET cannot open existing ASP.NET
Web projects. When you try to open an ASP.NET project, you may receive
following error message:
Unable to open Web project
'ProjectName'. Unable to validate that the file path
'c:\inetpub\wwwroot\webasp10' matches the URL path
'http://localhost/ProjectName'. A connection with
the server could not be established
To resolve this problem, install Windows XP Service Pack 1
on the computer running on Windows XP, and then install Visual Studio .NET. In
IPv6 scenarios, critical functions such as opening and creating Visual Studio
.NET projects, may fail if the service pack is not installed. To resolve the
problem, follow these steps:
On your computer running Windows XP, install Windows XP
Service Pack 1. To download Windows XP service packs, visit the following
