CIFS mounting only works with IP address and not hostname..

[WipeOut]

Hi,

I have just switched my fstab entries for my samb mounts to cifs rather 
than smbfs because its far faster..

The problem is that using cifs I have to use the server IP address for 
it to work..

I have tried from a command line as well and it will not connect and 
just gives an error when using the hostname.. Even if I manually place 
an entry in the /etc/hosts file it still won't work..

I did some digging and it appears that one proposed solution was to 
install mount.cifs which is apparently used for the name resolution but 
I can't seem to find how to install mount.cifs on Ubuntu..

Anyone got any ideas on why I am having to use the IP address of the 
server or how to install mount.cifs?

Thanks..
