Since it's just XP SP2, you might want to look at the XP firewall settings that were added by 
default during the SP2 update.  Get there Control Panel/Windows Firewall.  In there is file and 
printer sharing blocking on by default for notebooks and computers directly on the internet. 
Maybe you already looked at this.  Nothing else stands out.
