Kemp Loadmaster: Drop Connections on Real Server Failure & Drop at Drain Time End

I want to refer to two features within Kemp Loadmaster:
Drop Connections on Real Server (Exsist from 5.x) (Default not enabled!!).
Failure &
Drop at Drain Time End (New feature at 7.04) (Default not Enabeld!!)

Drop Connections on Real Server Failure

By default existing connections are not closed if a Real Server fails. This can lead to issues with Outlook clients if an Exchange CAS server fails. A solution to this is to enable the Drop Connections on RS Failure option which can be found on the System Configuration > Miscellaneous > L7 Configuration screen in the WUI.

When this option is enabled, LoadMaster tracks all the incoming connections and which Real Servers they are connected to. When a Real Server fails, all connections to the Real Server are immediately dropped, forcing the connections to reconnect to a different Real Server.

Enabling this option has the added benefit of allowing relatively higher Idle Connection Timeout values to be set as the danger of the client retaining a connection to a failed server is removed.

Drop at Drain Time End

By default existing connections are not closed when a real server is disabled. This can lead to issues with Outlook clients if an Exchange CAS server is administratively disabled. A solution to this is to enable the Drop at Drain Time End option which can be found on the System Configuration > Miscellaneous > L7 Configuration screen in the WUI.

When this option is enabled, LoadMaster will sever all existing connections to a disabled server after the L7 Connection Drain Time is reached. Clients will then be fored to reestablish a connection to one of the remaining Real Servers.

Active Directory Replication Status Tool

The Active Directory Replication Status Tool (ADREPLSTATUS) analyzes the replication status for domain controllers in an Active Directory domain or forest. ADREPLSTATUS displays data in a format that is similar to REPADMIN /SHOWREPL * /CSV imported into Excel but with significant enhancements.
Specific capabilities for this tool include:

    • Expose Active Directory replication errors occurring in a domain or forest
    • Prioritize errors that need to be resolved in order to avoid the creation of lingering objects in Active Directory forests
    • Help administrators and support professionals resolve replication errors by linking to Active Directory replication troubleshooting content on Microsoft TechNet
    • Allow replication data to be exported to source or destination domain administrators or support professionals for offline analysis
