If you’re running LCS (SP1), and if you’re familiar with the functionality of IMF for Exchange Server 2003, then you’re going to love this new version of IMF built specifically for LCS.

Live Communications Server 2005 Intelligent IM Filter application allows administrators greater flexibility in the protection of their instant message networks than the default IMFilter application that is installed on all Live Communications Server 2005 with SP1 servers. The default IMFilter blocks all URLs and file transfers, but the enhanced functionality that the Intelligent IM Filter permits several options for configuring how URLs and file transfers are handled. This new enhanced filter also includes configurable logging options and multiple performance counters for tracking network usage and identifying security or performance issues before they cause problems.
