Retrieving dead files from the Attic

[S I]

We're running the cvs Repo on a linux box with no shell access to users 
who're on the WinXP client side, except myself as the Admin.

A user accidentally committed files to the Attic and we need to retrieve 
them.  I've committed files to the attic many times before but we never had 
the need to retrieve.  I myself access the Repo via WinXP Dos prompt, as a 
client too to do my work and never login to shell except to create new users 
or do maintenance, etc.

Can I retrieve the dead files from winxp client side by being in my working 
copy's specific folder where the file was deleted, like so:

cvs –Q update -p -r (revision) foo.jpg > foo.jpg

cvs add –kb foo.jpg (only if binary)

cvs ci -m “Resurrecting the Dead!” foo.jpg

If this has to be done on the unix side, do I have create a working copy in 
my $home$ folder?  I need specifics please.  Your help is very much 
appreciated.  Thank you.
