Remote control of Windows XPIn the operating system Windows XP Professional built-in tool for remote computer management. You can from any room, where to eat another computer with any version of Windows (at least 95 OSR2) also with a modem or the Internet, own full access to the desktop of your family computer if it is connected to the network.
For the source, we need to allow the use of remote control. Moving to the "Control Panel -> System -> Remote Sessions" is also included there "Allow remote access to this computer."
In principle, now the computer is ready for remote control. However, one must find it somehow on the Internet. If your provider provides an external static IP address, then there is no problem. However, many providers (in particular, Stream) provide an external dynamic IP address - it is different once in a while, and in a few hours your ancient IP may already belong to someone else. To solve this problem, there are numerous DynDNS services - they give you a domain name that will point to your IP, and they constantly keep track of changes to your IP changes. In particular, such a gratuitous favor to eat on No-IP.com, there you can create your computer some third-level domain on the Internet, for example, mycomputer.no-ip.com. There blah blah allowed to download the customer - No-IP dynamic update client, which will be non-stop to contact the service No-IP.com and check / update your IP. I will not talk about the settings of this customer, but I can advise you not to change its settings, in addition to the "When updating via NAT / Router / Proxy address ONLY ..." parameter, which is better to set to "every 5 minutes".
Now, it is allowed to find a computer through the Internet. However, it is necessary to establish a connection with him. If, for example, you have an ADSL-LAN-modem, or just NAT, then you need to configure the "Port Forwarding" function for TCP port 3389 (the remote control works on it).
Also in the firewall you need to allow TCP-port 3389 to enter. I'll tell you on a sample of the Windows XP firewall (which appeared in another service pack). We follow the "Exceptions" tab also allow the "Remote Desktop Management" program (Fig. 2), then break through to the "Advanced" tab and enable the "Remote Desktop Management" service (Fig. 3) in the network connection settings. For the Agnitum Outpost v.2.5 firewall, in the Settings -> Applications menu, find svchost.exe, then use "Change -> Edit locations -> Create" to create a location.
Now let's deal with the client side. The customer for remote control is initially built into Windows XP. It is also allowed to find it in "Start -> Programs -> Standard -> Union -> Remote Desktop Connection". If you manage remotely from an earlier version of Windows, you will need to install the customer (you can either take it on the Microsoft website or send it from the c: \ windows \ system32 \ directory of Windows XP installed, mstsc.exe files are also mstcsax.dll.
So, we are going to connect. Set up integration with the Internet also launch the customer ("Start -> Programs -> Standard -> Union -> Remote Desktop Connection" or simply mstsc.exe). Click the "Parameters" button to gain access to additional settings (Fig. 5) in order to proceed to setting up client parameters. "Computer" is the address of your computer on the Internet. Here you must specify either a static IP address, or, for example, the previously mentioned dynamic domain such as mycomputer.no-ip.com.
"User" is usually the Administrator or any of the administrator accounts that exist on the managed computer. On the "Screen" tab, you can customize the size of the customer's window (I do not recommend to put more than 800x600). To optimize the work of a remote customer on modem lines, it is desirable to disable the "Sound on the remote computer" mode, which is located on the "Local Resources" tab. Is it done? Great, connect.
I note that when you install a remote control session, local access on a remote machine will be at once blablah blocked — you will also be prompted for a password. After the end of the session, the computer will remain in the locked mode until it is unlocked by locally entering the name and the password.
Well, that's all. I’ll add another significant security recommendation - don’t make admin accounts passwords (at least a couple of them in Windows XP –– created when you install the Administrator / Administrator is also yours) shorter than ten characters –– otherwise attackers can pick it up.
