blackadder,
I am afraid that other than the notes I gave you in my original post (such as to download the .dll yourself), I can't be off much help. I am on/using someone else's computer (Win98) and get the following:

C:\WINDOWS>perl -MWin32::AdminMisc
The Win32::AdminMisc module works only on Windows NT/2000/XP/2003 at C
+:/Perl/site/lib/Win32/AdminMisc.pm line 29.
Compilation failed in require.
BEGIN failed--compilation aborted.
[download]

Cheers - L~R
