I cannot see any of the QNAP shared folders from one of my PCs that is running Vista, QNAP Finder cannot find the device either.
I have no problems finding it or accessing network shares with any of the XP computers.
I can ping the QNAP and I can logon using the web admin interface.
Microsoft Networking is enabled in the QNAP, however the QNAP is in a different Workgroup to the Vista PC.
Also, with UPnP enabled on the QNAP I can at least see the NAS in the Vista Network and Sharing Center, however clicking on it opens the web admin interface. With UPnP disabled, I cannot see the QNAP in the Network and Sharing Center at all.
