SOLVED: I have finally managed to solve the issue. I compared the registry entries in the LanmanWorkstation entries on both my PC’s I have added RequireSecuritySignature to the parameters key and set it to 0 on my new PC and this has worked. I had the key enableSecuritySignatures bit not this one.
I stand by my comments that a user of ROON should not be going into the registry to change or add settings. This can easily be added to the install package at the developer end.
