VPN your machine is not a valid computer on the domain
I have had this a few times where a user has been using VPN then all of a sudden he gets this error, Your machine in not a valid computer on the domain? How does it lose touch with the domain and how can I correct this without having the user bring the laptop back in to sync up with the domain. He is a remote user and this would require a long ride to the company.

You could check if the machine is able to connect to a DC through the VPN to keep in synch (if you haven't done so already).
I was told that if the laptop has not been on the domain for over 30 days it loses sync? This guy never or very seldom comes in to the office. I myself have my laptop at home so when I am on call I do not have to bring my laptop home. This sometimes happens to me as well. I bring it back in and it syncs fine?
you could try to use lmhosts to point to your dc and your domain.

I found the reason here. It seems Trend Micro needed to be updated. This apparently allows the VPN client to run. It works. I updated TrendMicro and the VPN now works. Thanks all.
I found my own answer and this is the answer that works with this specific question. Trend Micro needed to be updated when off site. This causes a resync of the domain and the computer then once updated it will then connect fine.
