Norton Ghost 15 backup to Network Attached Storage under windows 7

I recently installed Windows 7 (clean install) and have been unable to get Norton Ghost 15 to backup to my NAS device (D-link DNS-323).  This worked just fine under Windows Vista.

 

Here's a summary of the errors I'm getting:

 

Error E7D10041: Unable to establish a network connection to <share name>

Error EBAB03F1: Multiple connections to a server or shared resource by the same user, using more than one user name are not allowed

 

If I change my destination to a share on a DIFFERENT machine running Windows 7, it works fine.  However, I can't get it to work with the NAS device.  The odd thing is, there is nothing else connected to the share I want to backup to.

 

Any help would be appreciated.

 

Thanks
