windows 2003 dfs link to XP share

Hey folks,

Is it possible to create a working dfs link to a Windows XP share? I can
create this link without any problems, but it appears that no clients,
including the XP client on which the share resides, cannot access the
folder. I thought perhaps this was a simple security issue for the share,
but even when I permit everyone access to the share, it remains
inaccessible. Are there server-side or client-side services that need to be
running or something?

Thanks for any advice,

Dave
