My colleagues and I are using different versions of QGIS (2.8.2, 2.86 & 2.14) on windows 8.1 and Windows 10.
When we open existing projects we get a "Handle Bad Layers" box coming up. We have each tried to reset the datasource link and when we do this we get a message saying "The specified network name is no longer available."
When we copy & paste the shapefiles onto our C drive we can open them in the project. After doing this, the original file path then seems to work but is lost again when the project is closed down & reopened.
We have referred this to our company IT consultant who has advise it is a QGIS problem and not a server problem.
I also have projects & shapefiles on Dropbox and these work fine. Can anyone clarify if this is a QGIS problem or a server problem?
