Welcome again.
This is Implementing Microsoft Windows Always On VPN,
and in this module, we're going to cover troubleshooting.
If you followed along with us in the course thus far,
you won't likely need this module because you will
have done everything correctly, everything will work perfectly,
and you won't encounter any problems at all.
I'm kidding.
Of course,
invariably there is going to be instances where
something doesn't work correctly,
and you'll need to perform some level of
troubleshooting to identify the problem.
This is more common during the configuration phase of the deployment,
but it also happens sometimes, you know,
post deployment when issues might arise later.
Unfortunately,
I can't cover every conceivable failure scenario and
possible error message you might encounter,
but what I will do is go over some of the most common error codes that
administrators may face in their day‑to‑day operations.
Many of the error messages you'll see as an Always
On VPN administrator are common,
and hopefully using the knowledge you gain from this module,
you'll be able to quickly identify the root cause and restore connectivity.
Troubleshooting is a combination of tools and methods,
and I'll go over some of the various techniques that I use when
troubleshooting Always On VPN for my customers.
Some of the tools are native to Windows,
which is helpful because there is nothing to download or install to
perform many of the troubleshooting tasks covered here.
There are, however,
some third‑party tools that can greatly simplify the task of
troubleshooting Always On VPN issues in some scenarios, and I'll discuss those a little bit later.
