I imported the project into Visual Studio .NET and tried to build. The old C++ iostreams headers are deprecated for Visual Studio .NET so in the interest of not getting tons of deprecated errors, I converted all of the iostream.h and iomanip.h includes to their new format (without the extension) then added 'using namespace std;' to the source files as needed. This builds on .NET and should build on VS6.
I've uninstalled my copy of Visual Studio 6 as I believe .NET is a large improvement, and anything old is bad for you, so if anyone wants to test this in 6, that would be great.
As a suggestion, I would suggest not adding the .sln or .vcproj files for .NET to the distribution, since you would then need to keep 2 sets of workspace / project files updated. Importing the .dsw and .dsp files into .NET worked fine for me.
Oh, I also removed the references to Chat Server and Login Server from the .dsw file. I'm not too familiar with the project yet, but I'm guessing those projects aren't distributed.
