An IIS 6.0 Web server always runs in one of two mutually exclusive application isolation modes. When you install FrontPage 2002 Server Extensions on an IIS 6.0 Web server, the server extensions run in the application isolation mode that you have chosen to run on the server. The application isolation mode you choose depends on what mode best fits your needs, and you can change the isolation mode after installation. At the time you install IIS 6.0, a default application isolation mode is assigned as follows:

• For clean installations, worker process isolation mode is the default mode.
  
  
• For upgrade installations, IIS 5.0 isolation mode is the default mode.
  
  

For more information about choosing an IIS 6.0 isolation mode, see Running IIS 6.0 as an Application Server.

Before you install FrontPage 2002 Server Extensions, consider the following guidelines:

• You must run FrontPage 2002 Server Extensions on a computer that uses only the NTFS file system.
  
  Before you install FrontPage 2002 Server Extensions on an application server, verify that all disk volumes on the computer are formatted with the NTFS file system. Windows provides a conversion utility (Convert.exe) that you can use to convert an existing file allocation table (FAT) or FAT32 volume to NTFS without losing data. If you try to install FrontPage 2002 Server Extensions to a disk drive that is formatted with FAT, your default Web site is not extended.
  
  For more information about converting FAT or FAT32 volumes to NTFS, see Reformatting or converting a partition to use NTFS in Help and Support Center for Windows Server 2003.
  
  
• If you upgrade from an earlier version of FrontPage Server Extensions, you must manually upgrade each FrontPage-extended Web site.
  
  If you are running multiple extended Web sites and you upgrade from FrontPage 2000 Server Extensions running on the Microsoft® Windows®  2000 Server operating system to FrontPage 2002 Server Extensions running on Microsoft® Windows® Server 2003, Standard Edition; Microsoft® Windows® Server 2003, Enterprise Edition; Microsoft Windows Server 2003, Web Edition; or Microsoft® Windows® Server 2003, Datacenter Edition operating system, you must manually upgrade each FrontPage-extended Web site. If you have a single FrontPage-extended Web site and you upgrade to FrontPage 2002 Server Extensions running on Windows Server 2003, the extended Web site automatically upgrades to FrontPage 2002 Server Extensions.
  
  

If you have a Web server that runs on Windows Server 2003 and that has multiple extended Web sites, you must upgrade all your extended Web sites to FrontPage 2002 Server Extensions.

Note
In FrontPage2002 Server Extensions, the lightweight server extensions option is no longer supported. When you upgrade an extended Web site to FrontPage2002 Server Extensions, it receives a full (not a lightweight) implementation.

For more information about upgrading your FrontPage-extended Web sites, see Upgrading from FrontPage Server Extensions and Office Server Extensions.
