Windows XP starts IIS, installing the VS.NET 2003 and then install IIS, and the result is created with the VS.NET 2003 to create a new project error, which cannot be connected to the server. However, the order of IIS is not critical, and IIS rear can be installed through the ASP.NET_REGIS.exe. And the fundamental problem is that the firewall on the computer is set to prevent the VS.NET to access the network, can't even connect. It seems that the firewall setting should be careful, after setting, other software has problems, sometimes I can't think of the firewall. However, this has not all been solved, and the XP partition is FAT32, which cannot give directory, and other NTFS partitions can not be set, which cannot let VS.NET's user group read and write. So I have to make NTFS reload. In addition, I found the system of the NTFS partition, and finally I can establish a project. But you can't debug, install MSDN, so vs.net online help, it is necessary to set up inetmgr, put the default web site-> directory security-> anonymous access and authentication control-> edit-> integrated Windows Authentication . It is finally moving.
