Samba mapping issue

I am using a wireless XP Pro laptop and everything works fine,
I have a LINX box with Samba running sharing some folders
I have mapped drives to the folders from XP and they are there OK, I ticked
the box for reconnect at logon. The mappings work fine

....but

If I restart the laptop the mapped drives in explorer have a red cross
through them and some software complains that it cannot find paths to the
shared drive

Opening the shared drive in explorer gets rid of the red cross and the other
applications can now connect

I seem to remember in Win ME there being an option to have windows open
mapped drives on startup - is this still available on XP

anyone got a work around?
