Disabling clipboard, Drive Mappings, client redirection etc within a RDP session

So you want to disable
* clipboard copy/paste
* Drive mappings
* printer mappings

fDisableClip , fDisableCdm, fDisableCpm, 

and you don't have the PC/Server on the domain?

Easiest thing to do is set it manually using reg query/add like so:

echo off
set server=%1
set passwd=%2
echo =====================================================================
echo %server% %passwd%
psexec \\%server% -u %server%\administrator -p %passwd% reg query "HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" | findstr /i fdisable

psexec \\%server% -u %server%\administrator -p %passwd% reg add "HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" /v fDisableClip /t REG_DWORD /d 0x1 /f
psexec  \\%server%  -u %server%\administrator -p %passwd% reg add "HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" /v fDisableCdm /t REG_DWORD /d 0x1 /f
psexec \\%server% -u %server%\administrator -p %passwd% reg add "HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" /v fDisableCpm /t REG_DWORD /d 0x1 /f
psexec \\%server% -u %server%\administrator -p %passwd% reg add "HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" /v fDisableLPT /t REG_DWORD /d 0x1 /f
psexec \\%server% -u %server%\administrator -p %passwd% reg add "HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" /v fDisablePNPRedir /t REG_DWORD /d 0x1 /f

psexec \\%server% -u %server%\administrator -p %passwd% reg query "HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" | findstr /i fdisable

 And if for some reason, domain PCs don't have it applied:

echo off
set server=%1
echo =====================================================================
echo %server%
psexec \\%server% reg query "HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" | findstr /i fdisable

reg add "\\%server%\HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" /v fDisableClip /t REG_DWORD /d 0x1 /f
reg add "\\%server%\HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" /v fDisableCdm /t REG_DWORD /d 0x1 /f
reg add "\\%server%\HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" /v fDisableCpm /t REG_DWORD /d 0x1 /f
reg add "\\%server%\HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" /v fDisableLPT /t REG_DWORD /d 0x1 /f
reg add "\\%server%\HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" /v fDisablePNPRedir /t REG_DWORD /d 0x1 /f

psexec \\%server% reg query "HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services" | findstr /i fdisable
