Symptoms

Sharepoint 2007 site thinks that the host server is the old server location
 

Diagnoses

When I navigate to K2 Site Settings tab and I go to the setting site. It shows the old decommissioned K2 server name. How do I change those settings to reflect the new K2 server? I have tried to re-run the K2 for SharePoint activating wizard, but it didn't seem to help.
 

Resolution

Issue was resolved per steps below:
-Use the SharePoint Manager 2007 to access the K2 hidden list.
For example:
http://portal.denallix.com/Lists/AF4EC0B37F8A48e5BE0E0CBB41B96BD4/AllItems.aspx
-Update the K2 hidden list – General > HostServer url to point to the new servername.
