• Before you install this release of IAS on a computer running the Beta 3 version, you must stop Internet Authentication Services and then uninstall it. (If you have to reinstall the release version of IAS at any point, you will also have to stop IAS and then uninstall it first.)

Known Issues with Internet Authentication Services

• In the setup program, Internet Authentication Service appears as a subcomponent of Internet Connection Services for Remote Access Services under Windows NT 4.0 Option Pack. You will have to enable the Internet Authentication Service checkbox to install this service.
• If you are installing IAS for the first time, the IAS cannot start until it is configured using the Internet Authentication Service Properties administration tool.
  
  To configure the Internet Authentication Service:
  1. Click Start, point to Programs, then point to Windows NT 4.0 Options Pack, then point to Microsoft Internet Information Server, and then click Internet Service Manager. The Microsoft Management Console (MMC) appears.
