Failed Connection Message


I have a WD MyBookWorld white edition and have been using it successfully and able to connect to it from both my iMac (OS Lion) and MacBook (OS Snow Leopard).

However, today I get a “connection failed” message when I try to connect to it via "Finder’ on both my iMac and Macbook.

The LED’s are moving slowly up and down.

I have re-booted both the MyBookWorld and my router and my internet connection is OK

Can anyone help please?



Have you try connecting the server ?
