Configure this string value to configure Workspace Control to connect to the Datastore using the MultiSubnetFailover = True connection property in the SQL connection string.

  • HKEY_LOCAL_MACHINE\SOFTWARE\RES\Workspace Manager (32-bit)

  • HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\RES\Workspace Manager (64-bit)







Ivanti strongly recommends using this registry setting only when connecting to a Microsoft SQL Server Always On Availability Group listener or SQL Server Failover Cluster Instance. Configuring it for any other Datastore connection scenarios can result in negative performance. Such scenarios are not supported.

The MultiSubnetFailover connection property is required only for the Workspace Control Console.

Configuring MultiSubnetFailover = True is not required with Microsoft .NET Framework version 4.6.1 or later. Workspace Control Agents and Relay Servers meet the specified .NET Framework requirement and do not need this registry setting configured.
More information about MultiSubnetFailover and .NET Framework is found in the following Microsoft article: SqlClient Support for High Availability, Disaster Recovery
