BRGUI for Windows Server

All of our SAP implementation on MS-Windows 2000 Server. Also, we have WEBAS 640 installed with 640 Kernel. How can I installed or configured BRGUI on Windows 2000 Server. In BRGUI Properties file, it was listed as rsh; but how can I connect to my Windows 2000 Server. Any help or hint will be greatly appreciated with good points.

Thanks
