We are running a Windows 2003 Server/XP Pro shop with about 30 servers and 70 desktops in a highly locked down environment. We are using RAdmin for remote control but are not very happy with it for a number of reasons. When asking our manager if we could just use Remote Desktop for device management, his response was that RDP used too much bandwidth. Are there any white papers out there that are suitable for presenting a case that it does not use too much bandwidth? Personally I know it doesn't, but in order to convince him to let us use it we'll need solid proof.
I would encourage you to measure, maybe with a tool like Network Monitor or just with perfmon / perf counters and compare. i.e. how many bytes were sent on teh network to do the tasks you usually do with Radmin, and then do the same with Remote Desktop then compare.
One important thing to keep in mind is that the performance of the Remote Desktop protocol is improving release to release. So whenever you the servers/desktops will upgrade to some more recent operating system (Windows 7 and Server 2008 R2 would be great for instance), you will get some dramatic performance improvements including in bandwidth usage compared to Remote Desktop on XP. If you ever have the opportunity to test Windows 7 along with Server 2008 R2 (free time limited versions are available) in a test environment, please do so.
