Greetings. 
Time ago i posted about what to do with some pentium pro PCs with very limited hardware. 
Some suggestions were install puppy4x or tinycore, but i really would rather that they would not do any kinda of tasks. 
Then i installed windows XP suricata (a very "light" mod). 
Today i tried to use mi AMD e1 laptop with w7 as server, and the results were very good. 
The NICS of the "clients" are 10mbits, then i guess that i had better use RPD instead VNC. 
Then now i am a bit "decided" about what to do. Now i guess that i will need a RDP server, and i do not really matter what would be linux windows... ubuntu puppy opensuse... Anyone. And if the RDP server would be "lighter" in the clients, it is another good point. 
Finally, i am here asking for suggestions of any RDP server multiuser (at same time) for use with those windows xp clients. 
Event if a linux client would be lighter than those xp, it would be greater then. 
Finally, thanks a lot. I will ask this in ubuntu puppy and opensuse and TC forums. Thanks a lot
