Diagnoses

This is a bug that was discovered in 4.6.9 and is fix in version 4.6.11.
 

Resolution

To resolve the issue pre-4.6.11 release, please navigate to the 'BrokerManagement.exe.config' file located at (C:Program Files (x86)K2 blackpearlServiceBroker). How does the 'SmartBrokerDB' connection string currently look?

<add name="SmartBrokerDB" connectionString="Data Source=PANDD-SP2013;Initial Catalog=K2;integrated security=sspi;Pooling=True" providerName="K2BLACKPEARL" />

If applicable, please update the "Data Source" (your SQL server) and "Initial Catalog" (the K2 database name) parameter to the appropriate value in your environment and retest.
