K2 Blackpearl Re-Resolve Group to Users

K2 Blackpearl Re-Resolve Group to Users

We have a system built around the K2 Blackpearl workflow engine that routes requests to the appropriate destinations. We switched a number of users from one active directory domain to an entirely different one, which K2’s cache wasn’t aware of. This caused some users to be missed when resolving the workflow destination active directory group to its members.

Force K2 Workflow Activity to Re-Resolve AD Group Destination to Members

The first thing we need to do is force K2 to refresh its cache for the problematic active directory group.

  1. Navigate to the server where K2 is hosted.
  2. Find the ForceIdentityServiceRefresh application shipped with K2. For us, that’s in the C:\K2 folder.
  3. Enter the Group name, select the “Group” object type and check each checkbox to force a full cache refresh for the given group.K2 Cache Force Identity Refresh
  4. Click the Clear Identity Cache button.

Now that the cache is cleared K2 will have a reference to the latest members associated with the group in question. It’s time to make the K2 workflow re-resolve its destination:

  1. Open the K2 Workspace.
  2. Navigate to the Management Console.
  3. Within the Management Console menu tree, navigate to the Instances node of the workflow process that has a problematic instance, which is typically under the following path:

    K2ServerName -> Workflow Server -> Processes -> Your.Process.Name -> Your.Workflow.Name -> Instances

  4. Search for the workflow instance you want to re-resolve destinations for, select it, then click Goto Activity.K2 Workflow Instance
  5. Within the Goto Activity screen you’ll see a list of all available activities associated with the workflow. Select the same activity the workflow is currently at, then press OK.K2 Workflow GoTo Activity

The result of following the above steps will force the given instance of your K2 workflow process to re-evaluate the selected activity, effectively causing a re-resolution of the destination group to its members from K2’s refreshed cache.

Active Directory Users and Computers Missing on Windows 10

Active Directory Users and Computers Missing on Windows 10

If you’ve ever needed to maintain any information in Active Directory, you’ve undoubtedly utilized the Active Directory Users and Computers app. According to Microsoft:

Active Directory Users and Computers is a Microsoft Management Console (MMC) snap-in that is a standard feature of Microsoft Windows Server operating systems. It can be used to administer and publish information in the directory.

I recently received a new laptop from work and had to go through the pains of installing all the necessary (and unnecessary) programs. After thinking I finally finished I realized Active Directory Users and Computers was missing. It turns out my WIndows 10 machine didn’t have the Remote Server Administration Tools (RSAT) installed.

Install Remote Server Administration Tools on Windows 10

Microsoft makes installation of the remote server administration tools fairly straightforward. Start by navigating to the Remote Server Administration Tools page, then download the installer and step through the installation wizard. Once the install finishes you may need to reboot your machine. After rebooting, you should see the Remote Server Administration Tools as an enabled windows feature:

Now that Remote Server Administration Tools is enabled you can load up the Active Directory Users and Computers application:
