RDP - connecting local drives to remote host

Archived from groups: microsoft.public.windowsxp.work_remotely (More info?)

Hopefully I'm not missing something fundamental here; I
have a laptop RDP'ing via dialup to a desktop. The laptop
is a member of the domain that the desktop belongs to, all
running XP Pro. The user on the laptop's domain account
is a member of laptop's local administrators group. When
he makes his RDP connection the local drives show up on
the remote host but I try to access, for example, the
floppy drive I get the error message "\\tsclient\a is not
accessible. You might not have permission to use this
network resource. Contact the administrator of this server
to find out if you have access permissions."
