Just wanted to update this thread in case it may help someone else...
For some reason Windows was having problems trying to access the Backup NAS by it's name...
Mapping it by name didn't work either. Finally, I tried mapping the box by it's IP Address and all problems were solved!
Steps used:
From "My Computer" select the "Map network Drive" tab.
Then instead of browsing, and using the name from the tree (on the left) just enter the boxes IP Address.
EX: \\192.xxx.x.xxx\name (insert your info for x's and name)
Just glad I got my files back!!!
