• You must remove all previously installed hotfixes for Live Communications Server 2005 SP1 before you install this update.
• This update cannot be uninstalled. To remove the update, you must remove Live Communications Server 2005 and then reinstall Live Communications Server 2005 from your original Live Communications Server 2005 CD. For more information about how to remove Live Communications Server 2005, see the "Removal information" section.
• We recommend that you back up your database before you install this update. This will enable you to restore back to the last working state of the database in the unlikely event that the update fails to install. Then, back up your database again after you install this update.
• Do not restore any backups that you made before you installed this update. If you restore these backups, you will effectively remove the update from the back-end database only. This leaves the front-end servers unable to connect until the update is reinstalled on the back-end servers.
• You must have administrative permissions to Live Communications Server and to the back-end server that is running SQL Server to install this update.
• If the back-end server that is running SQL Server is hosted on a server that is running Windows 2000 Server, you must install Windows Script Host (WSH) version 5.7 on the back-end server before you try to install the update. To download WSH version 5.7, visit the following Microsoft Web sites:

• If the back-end server that is running SQL Server is hosted on a server that is running Windows 2000 Server, use one of the following methods:
  • Install the Windows 2000 Support Tools by using the Windows 2000 Server CD.
  • Copy the reg.exe utility from the CD, and save the utility to the following folder on the server:
    %systemroot%\Program Files\Microsoft LC 2005\DBsetup
• You have to apply this update only on the active node of the SQL Server (active/passive) cluster.

We recommend that you install this update in the following order:

1. Perimeter network servers
   Install the update on the Access Proxy server first. Then, install the update on the branch office proxy servers and the directory servers.
2. Internal servers
   Install the update on the back-end server that is running Microsoft Office Live Communications Server 2005 Enterprise Edition first. Then, install the update on the front-end server that is running Live Communications Server 2005 Enterprise Edition, the server that is running Microsoft Office Live Communications Server 2005 Standard Edition, and the address book server.
3. Administrative tools server
   Install this update on the server that is running the administrative tools last.
