How to have 2 or more users on a PC via Remote Desktop

There is a fairly simple way to have a good pc and that several users to connect to the PC and can work all at once. For example at home you can have a well equipped computer and several "loose" computers that connect to the "good" computer. Another example would be a classroom in a school with old computers that connect to a new computer (called "server").
For this, the server PC will need to have enough hard drive, be fast and above all have a lot of memory (4 GB or more). The basic scheme is the following:
In our case, we have a server PC (with Windows Seven) and 3 PCs (Windows XP) to work remotely with Remote Desktop Server. Everything will be connected via network (using the Switch). This would not matter if the PC Usuario1es a bad old PC, the speed depends on how good the server and run programs that use memory Server.
The steps to get to have 2 or more users on a PC via Remote Desktop are:
1. Go to the Server and create the accounts "User1", "User2" and "User3" (or necessary). This is done with the "Button Start -> Control Panel -> User Accounts and Family Safety -> Add or remove user accounts".

2. On the server, go to System Properties and the "Remote" tab, click the "Remote Desktop" box, check the "Allow users to connect remotely to this computer".
This is done by clicking on:
Button Start -> Settings -> Control Panel -> System and Security -> System -> (1) Advanced System Settings -> (2) tab "Remote Access" -> (3) Enable the "Allow connections Assistance remotely to this computer "-> (4) Select the option" Allow connections from computers running any version of Remote Desktop (less secure) ".

3. At the same location as step 2, click the "Select Remote Users" button and select the users "User1", "User2" and "User3". Now give the "OK" button and then again "OK". 
4. Now click on the client PCs that: (1) Start button -> (2) Programs-> (3) Accessories -> (4) Remote Desktop Connection.

5. If you can not connect to the server using the options: "(1) Equipment: -> View more", connecting directly by IP Server by typing eg "192.168.1.3" or "\\ 192.168.1.3 \" (without quotation marks) or a similar IP.

In the box (1) is where you have to type the IP of the server, with the "Options" button (2), you can configure more advanced things, for example you can automatically connect to the server, without asking the user name nor the password.
6. There is a problem, by default Windows Seven will not let connect to multiple users simultaneously. To fix the geniuses of deepxw.blogspot.com.es are scheduled software that easily fix the problem:

• Go to your PC server and download this software: Universal Termsrv.dll patch (if the link above does not work, we have a copy on our server ).
• Simply download the program, if you have a 32-bit Windows run the "UniversalTermsrvPatch-x86.exe" program. Or if you have installed a 64-bit Windows run "UniversalTermsrvPatch-x64.exe". Once you have executed the corresponding program, click the "Patch" button. Finally restart the PC.

And finally, if anyone finds it useful:

If the server has Windows Vista or Seven or later, and before the start is entered directly without asking the user and password, you can fix running (press the "Ctrl + R" keys) a program of Windows called "netplwiz ". Once running, select the desired user, and uncheck the box that says "Users must enter a user name and password to use this computer".
