on 56b the project file is located on /graysvr/GraySvr.dsw

but note that this "dsw" file extension is really old from pre-historic Visual Studio 6 (1998 ~ 2003) and it's not compatible with Visual Studio >= 2004. So you have to find a way to install VS6 or convert the old .dsw project file into .vcproj (VS2004 ~ VS2008) or .vcxproj (VS2010 ~ VS2017) using an newest Visual Studio. After you find a way to compile the project file, probably it will return many compile errors because old codes usually are not compatible with newest compilers, so all these errors should be fixed manually

and after you take many hours/days to finally compile an "working" 56b build, it's also not recommended use it on a live server because it have tons of security vulnerabilities. So honestly it will be much easier, faster and secure just use sphere 56c/56d instead 56b
