We have an issue on our network that when we transfer files from site to site using windows the transfer drops and we get the error message "network not available". It doesn't happen all the time but 9 times out of ten it does! Some tunnels work better than others. We currently have 4 sites.
I have posted on another forum. We have tried many things but no one has been able to resolve the issue so far. Please check my other post for an update.
