Because of the size of the images being distributed to the target computers (500 megabytes [MB] to 4 GB), computers must have a high-speed, persistent connection to the servers used in the deployment process. These servers need to be on adjacent subnets to the target computers to ensure high-speed connectivity to the computers.
Note Network-based deployments using MDT are not supported for wireless networks. Use media-based deployments for computers connected by wireless networks or networks with slow or unreliable connectivity.
If the organization cannot provide sufficient network capacity to deploy images, software, and migration data to computers, perform one of the following actions:
· Temporarily place the appropriate servers (for example, servers hosting the various shared folders or the server running Windows Deployment Services) closer to the target computers for the duration of the migration.
· Temporarily move the target computers to a staging area where the computers can be deployed, and then return them to their original location.
· Store user state migration data locally on the target computers.
· Perform automated deployments locally using media deployments in LTI.
In addition to network capacity, you must enable the appropriate network protocols and traffic. For example, if you want to initiate LTI, ZTI, or UDI deployment using Windows Deployment Services and multicast deployment, you must enable multicast traffic between the MDT infrastructure and target computers.
