General

What are the Operating Systems supported by OS Deployer?
OS Deployer supports a wide range of Windows desktop and server operating systems. For the complete list of supported operating systems, refer to the System Requirements page.
What are the ports used by OS Deployer?
For the complete list of ports used for OS Deployment refer to the this page.

OS Deployment

Does OS Deployment support Windows Surface Pro?
Yes, OS imaging and deployment is supported on Windows Surface Pro machines.
Why is WinPE media required?
WinPE media is required to boot the machines in to Windows Pre-installation environment to perform deployment and offline imaging.
How is OS Deployment Licensed?
OS Deployment supports machine based licensing, that is the number of workstation and server machines on which you want to perform deployment. Here the licenses are tied to the machine's MAC address and once you purchase a license for a machine, you can perform any number of deployments on that machine. Depending on the operating system, you need to have either a workstation or a server license. E.g., to perform deployment on 100 workstation machines, you need to purchase 100 workstation licenses.
We have Dell and HP machines in our organisation. Does OS deployment support deployment of image on dissimilar hardware?
Yes, you can deploy images on dissimilar hardware as hardware-independent imaging is supported in OS deployment.
How to delete a driver repository?
A driver repository is used to store the drivers which are collected during image creation process. You can delete the repository from the product console itself. However, the repository will get deleted only in the UI and the drivers in the network share has to be manually deleted by the user. It is always required to have at least one configured driver repository to store the automatically collected drivers.
When will the driver repositories get synced?
All driver repositories will get synced every 4 hours.
Where will the applications be replicated for remote office deployments?
The applications required for remote office deployment will be replicated automatically to the Endpoint Central Distribution Server installed location (<DesktopCentral_DistributionServer installed location>\replication\osdrepository) in the Distribution Server computer.
Where will the drivers be replicated for remote office deployments?
The drivers required for remote office deployment will be replicated automatically to the driver repository available in the remote office.
How to copy an image from one image repository to another?
Currently, the image has to be manually copied from one repository to another. After copying the image to a new repository, you have to modify the repository path in the image details. To modify the repository, select the image and view the image details. Here, near the image repository, select the edit icon to modify the repository path.
How does OS Deployer activate the Windows license?
  • OEM license: If the Windows OS version of the image is the same as the OEM license, then the license will be automatically activated.
  • Volume-based license: Let us assume you've created an image by imaging a machine with a volume-based license. Depending on the availability of the license, if you deploy it to another machine the license will be automatically activated.

PXE Boot Server

What does PXE boot stand for?
PXE boot stands for Preboot Execution Environment — a network booting process using a DHCP or TFTP server that enables computers to boot via network-based software instead of local drives.
What does PXE mean?
PXE (Preboot Execution Environment) is a client-server interface that allows computers to boot over a network.
How to ensure clients from other subnets can boot using PXE?
If the OS Deployer server, DHCP server, and client are on the same network, PXE booting can be extended to other subnets using DHCP relay or IP helper configurations.
How to PXE boot computers over LAN?
Configure DHCP Option 66 with the OS Deployer server IP and Option 67 with the appropriate boot file (Legacy or UEFI). Then boot clients through the LAN.
What is a PXE server?
The PXE server in OS Deployer operates as a Windows service alongside the Central Server, enabling OS image deployment across networks.
What is PXE boot in Windows?
PXE boot in Windows allows network-based OS deployment across multiple devices simultaneously using a DHCP and TFTP-based process.
How do I run a PXE boot?
Configure your DHCP server with the appropriate options and initiate boot from LAN on target devices. PXE will automatically fetch OS deployment data.
How to enable PXE on a server?
To enable PXE on an Intel NUC:

  1. Enter BIOS setup using F2.
  2. Navigate to the Boot Menu.
  3. Uncheck Boot Network Devices Last.
  4. Enable UEFI PXE & iSCSI.
