• Installing a one-server topology on Windows Server 2008
  
• Installing a two-server topology on Windows Server 2008
  
• Installing a three-server topology on Windows Server 2008
  
• Installing a four-server topology on Windows Server 2008

To install Client Security SP1, connect the appropriate server to Microsoft Update or to WSUS. For detailed instructions on how to install Client Security SP1, see Problems and update scenarios that are addressed in Forefront Client Security Service Pack 1 (http://go.microsoft.com/fwlink/?LinkID=126628).

Note:
Client Security SP1 is a server-component upgrade only; you cannot install it on your client computers. If you are using Client Security in a multi-server topology, you only need to install SP1 on the collection server and the management server.
