How to create maltiple instance of single PC ?

I want to know the Device Name as well its details witch is used to create multiple instance of a Single machine.
Ex. Suppose I have a powerful server and want to connect multiple screens by creating new instance for every screen like single Screen is treated as a separate machine. (Like Virtual Desktop)
Please advice.

Not sure, but you might be talking about a thin client?

Google it and see if it matches your thoughts.

NEW Year Greetings.

Probably as a CyberCafe owner ( probably 10 systems ), user wants
to monitor , all the customers desktop screens . web sites being accessed etc.
Like DVR remote monitoring.

Thanks for the greetings --- wishing you well too!

You might be right. I think he needs to do his homework on multi-user operating systems.

He might want something like citrix, but I never used this, and, as I've given up Windows, now probably never will.

Option 1:
I think , you have guessed correctly the user's requirement.

A trial ONLINE is available for Linux users too.
Citrix Systems, Inc.
Video shows different OS'es screens access.

Option 2;
May be sharing Files/and folders in LAN mode will be cheaper option.

Thread starter has to respond. May need on site professional help.
