Microsoft has released an update for Microsoft Windows MultiPoint Server 2011

Install this update to resolve an issue where local and remote stations that are configured to use custom Remote Desktop Services (RDS) listeners do not display in MultiPoint Manager when a user logs on to one of these stations after MultiPoint Manager has started. You should consider applying this update under both of the following circumstances:
- You are using a local or remote device that uses custom, non-default RDS listeners.
- You want the MultiPoint Manager user interface to dynamically update as these devices are used to log on when MultiPoint Manager has already started.

Note: This update is cumulative, and also includes the update discussed in the following KB article: KB2530453
