WD Legacy Products Other Network Drives

I  cannot log in to my BWEI through WD DIscovery… It recognizes the drive and I can access the “configure” screen and get into the basic and advanced screens, but when I try to access “browse network shares” it wants a "localhost.localdomain username and password and neither the BWE1 , WinXP admin  passwords will work.

What is the "localhost.localdomain " password???  HElp
