I'm currently running IT for a small business that stores most of their files on a VPN hosted at a remote location. Most of the PCs are running XP, and have never had any trouble with the VPN. There is one laptop, however, that has Vista Home Premium on it. When I first started with the company, this laptop was having trouble with the VPN. Sometimes it would work, sometimes it wouldn't. No rhyme or reason to it. The laptop was originally the owner's husbands that he used while he was serving in Iraq. It was also having issues with freezing and things like that, so I said, this still has all these military files on it, I don't know it's history or what settings have been changed along the way, we need to start fresh. So we reformatted the laptop. Upon reformatting, I still could not connect to the VPN. After much troubleshooting, I figured out that the
bind value needed to be copy and pasted into the
\Linkage bind value.
There were a few additional settings I had changed, but none of them have reverted to the original settings so they need not be mentioned. After making this change, the VPN worked flawlessly.
I was then leaving town for a few months so I had setup all their PCs so I could remote connect to them in the event of any trouble from the outside. As we all know, Vista Home does not allow incoming RDC, but I used the patch at this website:
and it has worked up until today when they called me and said the VPN was down on this Vista laptop. So I emailed them the patch, had them reapply it, and was able to use RDC. So I went into the registry, did the copy and pasting as mentioned above, rebooted the laptop, and the VPN worked like a charm.
What could be causing these registry settings to revert? It should also be mentioned the laptop user just also changed because the previous one found a new job. So there are possibly some new network connections for the new users home network, but I have not verified this. The owner of the business says that they had just applied a Windows One Care update, and that this was also done around the time the VPN went down the previous time on this laptop. I'm not so eager to point to the AV software as the cause of network registry settings being reverted though, but I suppose there could be stranger things.
Thanks for the help! Big points to whoever answers this one!
