Better late than never, I guess.
If you're using VC++ 2005 (or at least, the most recent version available from the MS site), you'll need to download the Microsoft Platform SDK for Windows Server 2003. (A quick search on the site should turn it up.) After you have it installed, you'll need to copy the bin, lib, and include folders from its program folder to the following folder: MS Visual Studio 8\VC\PlatformSDK. After you do that, you should be able to uninstall the Platform SDK. (There's also a way to set up the proper paths within VC++, apparently, but this is supposed to be the simplest solution, and it worked for me.) I managed to stumble across this in an MS support forum thread while in the middle of a much-appreciated help session with Turey; apparently, the absence of these library files from VC++ was "by design," which seemed to rather annoy many of the developers in said thread.
Now I just have to find time to start looking over the code and learning what's what...
Edit: Whoops, looks like this was already addressed elsewhere.
