How did you install the module Win32::AdminMisc in the first place? Did you do:

1. download the package
2. compile and install the package:

   perl Makefile.PL
   nmake 
   nmake install
   nmake test
[download]

Other than that, you have to be more specific about the exact error message you are getting, as there can be many reasons why a DLL won't load.
