Somewhere it has picked up an old name from when I was playing around trying to get it to work.
This can be removed from the /etc/hosts file. In PCC > Network & Internet look at the bottom where you can edit this file. Remove the entry that you do not want.
Also, this problem sounds like like a similar problem that I have had before with ip access allowed in the smb.conf file. Have you "configured" the samba server in the samba area of PCC? Click on PCC > Network Sharing > Samba Server . When this window opens click on Samba Server from the menu and go through the configuration. In one of the windows it will ask you what ip addresses you will allow. I usually put this in that line:
127.0.0.1 allows for access on that pclinuxos machine and the 192.168.1.0/24 allows for access from all machines on that ip subnet. You will want to change this subnet to your network ip.
Tex did an excellent write up on samba configuration just recently. It may even be stickied.
Hope this helps.
