With any technology application, problems will be realized during the deployment of the application in a real-world environment.

This chapter describes some commonly faced issues when deploying Live Communications Server 2005 SP1 within an enterprise, including concerns with Active Directory, enterprise Instant Messaging migration, remote access, international deployments, and implementing Live Communications Server 2005 SP1 for military or private sector use.
