Can't access Samba by host name
I'm running samba on my ubuntu 8.10 box within my home LAN. I'm trying to access the share via my Macbook and a Windowx XP box. I'm able to see the host on both machines but I get a permissions error when I try to connect. I'm able to access the share when I connect to it via its IP address but I can't via the host name.
Any ideas on what I need to do to fix this?
