The WDS Image can be deployed easily on 32-bit hardware and without any issues. The client computers have 32-bit hardware can easily locate WDS Server and pull the image from WDS Server but client computers having 64-bit hardware cannot locate WDS Server and thus cannot pull the image. The support for 64-bit computers must be enabled on the WDS Server.
To enable support for 64-bit computers, run the following commands on the WDS Server:
Go to command prompt with elevated privileges on WDS Server:
Wdsutil /set-server /architecturediscovery:yes
The above command enables support for 64-bit hardware on WDS Servers. The WDS Client which runs on Windows client computers is able to discover the 64-bit hardware after you run the above command.
