Third+party+programs+that+use+NDIS+drivers+may+not+work+on+Vista

If you have just upgraded your computer to Vista from XP, you might discover that some of your third party network programs, such as VPN clients, don't work in Vista.  This can also happen if you upgrade a beta version of Vista to the release version, or even if you upgrade one version of Vista (such as Home Premium) to another (such as Ultimate).

 It happens when the program uses NDIS drivers, and the problem is that the driver does not get installed in Vista. To find out what to do about it, see KB article 928229:
