Hi swtjanani
Compatability of IIS 7.5 and Visual studio 2003 on Win 7 OS
In 2003, Microsoft introduced a minor upgrade to Visual Studio .NET called Visual Studio .NET 2003,. It includes an upgrade to the
.NET Framework, version 1.1, and is the first release to support developing programs for mobile devices, using ASP.NET or the .NET Compact Framework.
Since Visual Studio 2003 will be out of lifecyle, I think you could consider use VS 2008, VS 2010/VS 2012 instead, at the same time you migrate from .net 1.1 to .net 2.0 or above,
Moreover, you could also learn Visual Studio product lifecyle below,
