I have a DX4000 and everything was finally working.
One of the workstations with Windows 8.1 failed to a point that it was easier to erase the hard drive and reinstall Windows.
The workstation has no problems connecting to the NAS.
When installing the “connect” software there was a warning that a computer with that name already existed and asked if I wanted to continue. I did because it was the name previously used on the computer.
Here is the problem:
when connecting to the nas via web, I know see that computer but it has an “orange” mark and says “connection is disabled”.
I’ve rebooted the NAS to see if that would work, no luck.
