Netgear ReadyNASRND2110 NAS drive asks for UN & PW?

Hi All, I’ve purchased a Netgear ReadyNAS Duo RND2110.  The NAS is on my network with its own IP address, host name and MAC address. 

 

Although I can browse to the backup directory on my NAS drive within Norton Ghost 15 the software insists that I enter a username and password.  There are no usernames and passwords associated with the drive but it won't continue without this information.

 

Does anyone have an idea as to how I get around this problem please?

 

Many thanks,

 

Alan
