Backup Destination not Available

Hi,

 

I have a problem my back up desitnation is not available.

 

I'm using three desktop xp pro pc's with norton 14, all three connect to a switch and the external backup hard drive is connected directly into the router via ethernet.

I can ping the hard drive for any pc, I cant browse to the hard drive using ie.

 

Any suggestions would be very welcoming.
