VB6 Dll works in Windows 2003 server but not in XP

Hello,

I created a Dll using VB6, when the dll is compiled in WIndows 2003 Server, works perfectly... But when i take the same source, and compile it in a Windows XP computer, the Dll doesnt do anything.

I even edited the code, and converted it into an EXE (calling the classes intrnally from the main module of the EXE) and the code works perfectly fine, but not as a dll being called from another program (but id does work in 2003).

Any ideas???

Thanks,

Alfred.
