samba - Feb 2004 - mapping network drives with XP

I am using the samba server that came with RH9 and I have setup shares and
users on the server that match my users on the Windows XP workstation.  I
can browse the the shares via viewing workgroup computers.  However, I can't
map a network drive to that share.  Windows keeps throwing the following
error: "System Error 53 has occurred - The network path was not found"

I was hoping that someone may have some insight into this problem.

Thanks

Mike
