Overview

GFI LanGuard agent deployment fails and the LanGuard console shows the following error in the Agent management window:

The agent failed to install.

Deployment log file lanss_v*_patchdeployment.csvcontains errors 1130 for the same time frame, similar to:

\\w.x.y.z\C$\WINDOWS\Patches" "warning","DeploymentEngine","Failed to create folder Error 1130: Not enough server storage is available to process this command"

Prerequisites

An account with local Administrator privileges.

Diagnosis

As a part of the Agent Deployment process, GFI LanGuard tries to copy files for deployment to the target computer to the following location:

\\<ComputerName>\C$\WINDOWS\Patches 

The 1130 error for the shared folder operations may occur if the IRP Stack Size on the server is set too low. To verify the issue open the lanss_v*_patchdeployment.csv log file, with the default location at C:\Program Data\GFI\LanGuard 12\Debuglogs folder, and search for the Error 1130 or Not enough server storage is available to process this command messages.

You can remedy the root cause by increasing the value of the IRPStackSize registry entry.

Solution

1. Open the Registry Editor by pressing Windows logo key + R at the same time, typing regedit in the Run box and then click OK.
2. Increase the value of registry key IRPStackSize which is explained in the following Microsoft article: IRPStackSize. 
3. If the error message remains afterward, increase the value of IRPStackSize more.
4. If the error still persists, certain 3rd party products can cause this connection to fail. Check the Windows Event logs both on the server and target the computer side for the relevant errors and security events, and add the exclusion to the 3rd party product configuration.

Testing

Open the LanGuard console, go to Dashboard > Overview, right-click on the target computer and choose Deploy Agent. Verify the results in the Configuration > Agent Management window.
