HomeDirectory is proably a property, not a method, so

$User->HomeDirectory("\\server\homeshare");
[download]

should be

$User->{HomeDirectory} = "\\\\server\\homeshare";
[download]

Win32::OLE uses a lot of AUTOLOAD magic, so both might be exchangeable. Well, at least, I do think the accessor version of the property without parameters, is equivalent to just reading the property:

$home = $User->HomeDirectory();
[download]

vs.

$home = $User->{HomeDirectory};
[download]
