access, and must have the necessary version of Microsoft Dial-Up Networking and any necessary service packs.
Some operating systems can require a VPN adapter. You can find Microsoft upgrades and service packs on the
Microsoft Download Center web site at http://www.microsoft.com/downloads/search.aspx
