Please check the following Software (Desklock) which is a powerful software to just provide limited and authenticated permission to Windows' combination keys and all possible administrators' duties are controlled by a password and also you can also define start up programs. It worths testing. regards |

Hi Experts, I also tried the solution SteBo provided: http://support.automation.siemens.com/WW/view/en/22326550 It should work with Win7 but itdoesn't. I tried to debug but it seems to work fine,but nolock or unlocking of the taskbar. Hope you can help out Jaap I used this script, it triggers fine and state switches from enable to disable but whithout any result. maybe it's an security setting in Windows?: #pragma code ("UseAdmin.DLL") #include "pwrt_api.h" #pragma code() #pragma code ("ALMXGINA.DLL") BOOL SetXGinaValue(unsigned int uiKey, BOOL *pbEnable, DWORD dwSize); #pragma code() BOOL bEnable; BOOL bOK; #define XGINA_ALLOW_SHUTDOWN 1 #define XGINA_ALLOW_LOGOUT 2 #define XGINA_ALLOW_CTL_ALT_DEL 3 #define XGINA_ALLOW_CTL_ESC 4 #define XGINA_ALLOW_ALT_ESC 5 #define XGINA_ALLOW_ALT_TAB 6 bEnable = PWRTCheckPermission(1, TRUE); bOK = SetXGinaValue(XGINA_ALLOW_SHUTDOWN , &bEnable , sizeof(bEnable )); bOK = SetXGinaValue(XGINA_ALLOW_LOGOUT , &bEnable , sizeof(bEnable )); bOK = SetXGinaValue(XGINA_ALLOW_CTL_ALT_DEL , &bEnable , sizeof(bEnable )); bOK = SetXGinaValue(XGINA_ALLOW_CTL_ESC , &bEnable , sizeof(bEnable )); bOK = SetXGinaValue(XGINA_ALLOW_ALT_ESC , &bEnable , sizeof(bEnable )); bOK = SetXGinaValue(XGINA_ALLOW_ALT_TAB , &bEnable , sizeof(bEnable )); printf("#I101: SetXGinaValue() - bEnable=%d bOK=%d (lock/unlock windows keys)\r\n", bEnable, bOK); |

Hi Cedric. We are using WinCC 7.0 SP3 +Update1. In my case the behaviour is constant: one computer is working all time, the others no. Regards

Did you check firewall and virusscanning? It could be that something is blocked. I had that behavior whtihin V6SP4 and WinXP . Good luck. it's me "Jaapie" not AutoGen_469046 |

Hi. The firewall is off and no antivirus is installed, as the computers are in a private VPN with no web acces. Ioan

Hello Molthoff Found the solution after a long time. I was also facing the same problem then started searching in internet but no good answer. Then tried by myself In Windows 7 : Open Registry Editor and go to the following path HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Siemens\WinCC\Winlogon\Permissions You can see all the blocked key combinations. All the values are Zero, that's why they are disabled. Make the values for each combination to One (1) to make then enabled. I hope this will help you. Thanks |
