I assume that no one has answered my query due to a lack of ideas. The problem I describe does seem to have appeared in a number of different guises with systems trying to access forms of NAS other than NASlite. I found a solution at http://forums.microsoft.com/TechNet/Sho ... tID=522208
that appears to address the problem. Here is the info from that entry:
I've recently worked an issue very similar to what you have described with Vista Business Edition OEM.
Symptoms, the error "The "\\servername\sharedfolder" does not exist. The file may have been moved or deleted. Do you want to create it?" comes up if a user copies a file from the Share, edits the file and then tries to copy it back. You are however able to successfully save the file locally ?
A second issue was not being able to rename folders/files on the Share. Again locally is fine just over the network is an issue.
Cause : Possibly the way the OEM vender packaged the OS.
Resolution : Create the parameters key in the following location :
Then within the parameters key, create a DWORD Value named FormatDatabase with a value of 1 (hex) then reboot the machine.
Does anyone see a problem with this parameter? It seems to have cured the "rename" problem, but maybe has some unintended/unforeseen consequences?
