All of the functionality in DameWare Remote Support, including installing, removing, starting, or stopping the Mini Remote Control Client Agent Service on a remote system, is accomplished by asking the Operating System on the local system to execute standard Microsoft Windows APIs. This requires local Administrator rights to the Operating System on the remote system, and uses either your current local logon credentials, or your current authentication to the remote system.
In addition to local Administrator rights, these APIs require the following network settings are enabled on the remote system:
File & Printer Sharing: ports 137-139, 445
Server Service: Domain environments only
NetLogon Service: Domain environments only
