Executing remote actions with Finder (classic)
Nexthink Finder is a Windows-only desktop application whose functionality is now available within the Nexthink web interface. Nexthink can now be used directly from a browser and most functions no longer require an additional desktop application.
Automatic and manual triggering
The way in which a remote action is triggered, whether manually or automatically, usually depends on the particular usage scenario.
Manual triggering is used in assisted service scenarios, where a support team member executes a remote action to help an employee solve an issue. The rest of the scenarios typically schedule the execution of a remote action either periodically or in response to the detection of a specific issue:
Assisted service
Self-help
Self-healing
On-demand data
Delayed first execution of automatically triggered actions
Once an automatically triggered remote action is saved, it is scheduled for execution. To avoid excess network and processing load, the Engine distributes the execution of remote actions so that not all actions run simultaneously on the target devices.
Thus, due to this distributed scheduling, the first execution of an automatically triggered remote action can be delayed up to its triggering period or, if the triggering period is longer than an hour, up to a maximum of one hour after it was created.
Maximum number of simultaneous executions
The Collector can execute two concurrent remote actions, on Windows and macOS. Even though technically possible, Nexthink does not recommend executing two remote actions simultaneously on a system. Executing one at a time ensures you keep the potential impact of your scripts on the system resources as low as possible.
Controlling script execution on the device
When a remote action is triggered either automatically or manually on a device, the payload of the remote action is executed on the device only if the script execution policy allows it. Define the script execution policy of a device when installing the Collector on that device. Optionally, modify the script execution policy of a device later with the help of Nxtcfg (the Collector configuration tool).
For security reasons, the script execution policy controls the remote action scripts that are allowed to execute on a particular device.
Signed by a trusted publisher or by Nexthink (default): the Collector runs on the device only those remote actions with a PowerShell script that is signed either by Nexthink or by a company whose certificate is listed in the Trusted Publishers certificate store.
Signed by a trusted publisher: the Collector runs on the device only those remote actions with a PowerShell script that is signed by a company whose certificate is listed in the Trusted Publishers certificate store.
Disabled: the Collector runs no remote action on the device.
Unrestricted: the Collector runs any remote action on the device, regardless of the digital signature of its script. Useful for testing purposes, but not recommended in production.
Executing your own signed scripts
The default policy lets official remote actions from the Nexthink Library execute on the device without requiring any additional configuration. If you choose to create and sign your own scripts for remote actions, add the signing certificate to the Trusted Publishers certificate store in Windows.
In addition, if your certificate to sign scripts was generated by a private CA (that is, a CA whose root certificate is not already present in the Trusted Root Certification Authorities certificate store of Windows), add the root certificate of the CA to the Trusted Root Certification Authorities certificate store. Similarly, if you used an intermediate certificate to sign your scripts, include the full chain of intermediate certificates in the Intermediate Certification Authorities certificate store:
Log in to Windows as an administrator.
Press Win+R keys to open the Run dialog:
Type in certlm.msc.
Click OK.
Click Yes to allow the program to make changes to your device.
Right-click the name of the desired certification store (e.g. Trusted Publishers) in the left-hand side list.
Select All-tasks > Import... from the context menu to start the Certificate Import Wizard.
Click Next to start the wizard.
Click Browse and select your certificate file.
Click Next.
In the dialog Place all certificates in the following store, click Next to accept thesuggested certificate store.
Verify the certificate to be imported and click Finish.
It is recommended not to import the certificates individually on every device, but to use an administration tool to deploy the certificates on all devices at the same time. Use Group Policy Objects (GPOs) of Active Directory to this end, for instance.
Results of remote actions
The outputs declared by a remote action are displayed in Finder. Each output defines a label that is used by Finder to name the column in the list of results of the remote action.
In addition to their defined outputs, remote actions return their status in a supplementary field called Execution status details. If difficulties were found during the execution of the remote action, the status field indicates it with an error message.
