This share does not share everything per se. Rather it appears to be
somehow selective. For example, the password lists (username.pwl) are not
shared, neither are many of the directories under there. The
sub-directories that were shared on my system were:
VMM32
IOSUBSYS
COLOR
IE4Setup
The first two contain VXDs (virtual device drivers I believe). The second
contains .ICM files, I don't know what they are. While the last contains
a directory named plugins and a single DLL. I believe we did an uninstall
of IE on this machine so perhaps it used to have the install software for
IE on it. That would be a nice feature, automatically share your install
software for IE.
Simply placing a file in that directory named x.dll isn't sufficient to
enable it's appearance in the list. The entry must be elsewhere, perhaps
the registry.
Easy way to make a difficult-to-detect trojan, add more files to the share
list under PRINTER$ then quitely take the files when nobody is looking.

I would tend to agree with you there.
