For Windows 10 Education edition Dell suggests using SonicWALL Mobile Connect to connect the VPN run by my educational institution. After installing and running SonicWALL Mobile Connect for the first time I am able to connect to the VPN without any problems. When I disconnect and try and reconnect again it fails with the following error message:
The network connection could not be found
Despite it failing to connect it can still detect if I entered my username and password wrongly which suggests communication at some level still occurs between me and the VPN. Windows Firewall has also been completely disabled during this process.
To help investigate the issue further I have created a virtual machine with a snapshot taken before the first connection to the VPN is made. This allows me to easily return the OS to a working state which ended up being more convenient than using a system restore point on my psychical machine.
At the moment the only idea I have is to try and isolate what changes are carried out during the connection process and undo them until I find the change that is preventing me from reconnecting. With thousands of registry changes made during this process I am simply looking for any suggestions for where I should focus my attention or other ideas to help troubleshoot the problem.
