Configuring UserDir on a windows machine?

Hello all,

I'm trying to configure apache to look at a series of user directories
on another server

I've added
UserDir "//server-001/*"

and found it works ... but as you may well realize, that's a bit of a
security hazzard

so i went on to try
UserDir "//server-001/*/public_html"

and found it will not work ... the error log shows that when using the
first directive
http://localhost/~username resolves properly to "//server-001/username"
however
when using the second it somehow gets set to looking for
"C:/docroot/~username"
including the tilde

I'm running Apache/2.0.55 (Win32) on a windows XP-Pro machine
a bug perhaps? anyone have any suggestions? there may be a way to use
regex
or alias to add the trailing "/public_html" to the UserDir

I've also noticed that if i try to include (un-comment) any sort of
additional
<directory> statement, i get an error when trying to start up the
server

any ideas on a way i can get this thing up and running?
