I'm running windows 7 RC1 64bit. I can get the storage device to show up but that only allows access to the devices webpage. I can't get it to recognize the nas as a computer. I used the vista driver but still no dice. I also made sure they were on the same workgroup. Any tips?
I too just installed Windows 7 RC1 64-bit, have gone through the same steps as you and I am getting the same behavior as you: I can see the NAS, but can't see the shares or map a drive to one of them. Windows says "network path could not be found" or something to that extent.
I am guessing D-Link will need to release Windows 7 drivers or at least for the 64-bit edition (maybe the Vista 32-bit drivers work fine).
