You can install a service account proxy on the same physical or virtual server as the Recast Management Server and/or a Recast Agent Gateway. It's possible to add a Recast Proxy during or after Recast Management Server installation.
If the proxy is being installed in a different domain than the Recast Management Server, the Recast Proxy must be deployed separately after Recast Management Server installation. See Install Recast Proxy Separately.
