I assume that your deployment on are stuck on "Performing preliminary checks".
To try and resolve the issue with the deployments being stuck at Performing preliminary checks, we would recommend the following steps:
Check that your Lansweeper service is not stopped when deploying. If the service is stopped the deployment will stop but will show the same message Performing preliminary checks.
- Stop your Lansweeper Server service.
- Restart the client machines where the deployment is running on or kill the deployment executable on the client machines (remotedeployment_x86/64.exe).
- Clear the Installer logs by using the Clear Logs report option in the left-hand pane under Deployment\Installer Logs.
- Restart your Lansweeper Server service.
Try deploying to a single asset that stayed on Performing preliminary checks before.
