You will have to install whatevere is not installed before you can install VS.net 2003.
On computers running Windows XP, you must install Windows XP Service Pack 1 before installing Visual Studio .NET 2003 if your projects rely on IPv6. In IPv6 scenarios, critical functions, such as opening and creating Visual Studio .NET projects, may fail if the service pack is not installed. If your projects do not rely on IPv6, installation of the service pack is not required.
