If you’re like me, you’re already a huge fan of Windows 7. Its simply the best OS Microsoft have produced to date. But as good an operating system that it is, it has one serious draw back. Most existing VPN clients don’t work with it.
In my line of work I use 2 custom VPN clients at the moment, and there simply isn’t a work around to get these clients working, except for running XP Mode.
Microsoft assure that VPN client vendors are upgrading their software to work with Win 7, so future versions should be fine, but at this very minute, if you’re using VPN on a daily basis, then be aware of this issue, more information can be found here: http://technet.microsoft.com/en-us/library/dd787668%28WS.10%29.aspx
