Nelson,

dynamically loaded plugin dlls which in turn require other statically  
compiled libraries is where Windows dll hell starts to get really  
ugly. Windows tries to locate your sde libraries either in one of the  
directories contained in your %PATH% (probably set by setenv.bat but I  
don't use MS4W so I can't help you there) or, preferably, in the  
application's folder. By that, if I'm not mistaken, they mean the  
directory which the main executable image of your app is launched  
from, so probably the one containing mapserv.exe (or maybe the one  
where libmap.dll resides?). It's definitely not going to work if you  
place them relative to the plugin inside your specialplugins folder as  
that dll is dynamically loaded into the main application's process  
space. What I'm saying is that Dependency Walker won't help you in  
this case if you launch it directly on msplugin_sde_92.dll, because  
what counts is what mapserver.exe/libmap.dll sees, not the plugin.

Still, if all fails, you could always just drop the sde libs into c: 
\windows\system32 but I'm sure with some trial and error you'll find a  
place where they get picked up correctly.
