Reverts changes made to the server during the initial server configuration. This includes changes made by either the /initialize-server option or the Windows Deployment Services MMC snap-in. Note that this command resets the server to an unconfigured state. This command does not modify the contents of the RemoteInstall shared folder. Rather, it resets the server's state so that you can reinitialize the server.
WDSUTIL [Options] /Uninitialize-Server [/Server:<Server name>]
Specifies the name of the server. This can be either the NetBIOS name or the fully qualified domain name (FQDN). If no server name is specified, the local server will be used.
