First change the name of your linux box.
edit the file /etc/sysconfig/network and give hostname there,also make changes in /etc/hosts file. check /etc/samba/smb.conf file give same workgroup as your windows Xp work group.restart the linux machine,
sometimes due to iptables samba gives the problem so stop the service of iptables . now try to connect .
All the Best
