How do I remove a server listing from the management console
Diagnoses
K2 has a self-discovery protocol that finds other K2 servers on the same subnet.
Resolution
If you would like only the servers you've specified to show up in that bar, you can disable the Autodiscovery protocol as per this KB: http://help.k2.com/KB001221
Only servers that you want to add explicitly will show up in that sidebar. (Alternately, you can modify the server to keep it from broadcasting to other servers)
You can also check the Management.xml file for that server, under the and nodes, and remove it from there if it has been added.
