NComputing software touch a lot of Windows personnal parameters like

• "Display window while moving"
• Remove visual style 
• Don't  turn off monitor
• Lock Energy parameters to "Presentation"
• And many more i think ....

Why doing this ? Why don't let the users choose what they want ?

Even if we have to disable visual style or turn off energy parameter to get NComputing software work better, why locking them ?

If i want my host-monitor to turn off after 20 minutes, how can i do ? it's to be a little more green ... like are the L-series ....

You can say : turn off the monitor's power switch .... yes but it is the principe .... you can even say "use a software that power-off the monitor", yes but windows can do it alone ...

I have even many more question to this globally quetion ... but i'm better a french writer than a english one ...

My point of view of the NComputing software would be to "only enable a multi-user windows access" with audio service and many more thing, a little like Windows RDP do .... but don't touch personnal parameters or custom parameters ...

On a Terminal Server, even if RDP is activate, we can change Visual Style / Energy parameters / etc ...

But the situation with the monitor to turn off and any other parameters is on the Host computer not on remote terminal.

I understand your point of view. And you said  I tell my users to "log out" and turn off the monitor and box : I do the same.
But where I am not agree with you is that Windows can differentiate each session and each parameters of each user connected.

For example, NComputing disable the "show window contents while dragging" option, but we can re-enable it manually, at every new session.
This setting doesn't affect other session connected to the host, this is the same for some other effect like "show shadows under menus" or any other visual effects. This, even, doesn't consume a lot of bandwidth in a 100Mb/s network (even with 30 users), on the contrary, this add, the so called expression, "a better user experience".

For the monitor to switch off, this is only at the host side, not terminal side, and that, Windows can differentiate the user which is connected to the console or the user which is connected remotely, so he can turn-off the monitor on the console.

Another example too, NComputing software make Windows skip "the search for a driver in a specific path" option when we connect a device that he does not recognize (yes, we can add/change a reg key to put the specific path). But Why ? Does this really affect the software ? I don't think.

What I would like is that NComputing should make a recommendation list and let the sysadmin do what he wants, if he does not want to follow the recommendation, it is his problem. NComputing should not block features that the OS has.

I have installed the software with an L230 terminal and i think that roms ideas are not so bad and he's not the only one having a problem with the working mode of the server software.

I also would like to have my host go to standby when their is no activity, for example when all clients are disconnected. As NComputing is changing the power mode, I can't even put my computer manually in standby; I first have to disable multi user mode, restart and then change power mode manually. (I'm using the terminal only randomly).

I think you are asking for too much.  If you want a terminal services environment, then purchase terminal services and all the required hardware.  I think you must make allowances for what they are accomplishing with a non-server OS and the fact that if they let people change things that are important to the use of their software that people will do that and screw up their setup and claim how bad the Ncomputing is.  You know it happens.

As for the standby mode,  I would of course like my hard drives to spin down when nobody is connected, so what I do is use a UPS and a RPS-ATX Computer System Reboot Device  to schedule my power downs and restarts.
