Thank you VERY much for this post suggesting to Reset to Default Settings without impacting all of the data on my DNS-323 drives so that I could access my files. This solution also resolved an access problem that I was having on my new WIN7 PC. I was able to map the drive but didn't have the permissions to access it. Windows Explorer would just sit and spin for a long time and then return an error, but not any longer. I've spent the past 3 Days trying to resolve this issue and D-Link Phone support was no help either. THANK YOU!
