Updated Jan 2018 with amazingly high success rate! When the world moved to 10, those would could not and would not move their legacy Cisco VPN software would have hit some problems while using VPN on their newer Windows 10 machines. This is because the legacy Cisco VPN-client is not supported under Windows 10 and , it probably will never be supported anymore. Yet, for some reasons, there are still users like myself who are not able to use the newer Cisco AnyConnect, as it might not be supported by their existing VPN infrastructure or some other reasons. Faced with similar issue, I searched for possible solutions online and tried different ways of overcoming the issues, which is often a hit and miss affair. This is the newer guide for Windows 10. If you are looking for the Windows 8 guide for Cisco VPN client,. This tutorial is becoming even more robust as more and more reported success and provided additional tips to improve the process, and I have enhanced the tutorial, to make it as foolproof as possible for you. Many reported they can now work from home, or use a single machine to access VPN instead of two machines, or simply made their life much simpler! Thanks to the Gleescape. Most users will face the first error, which says: Secure VPN Connection terminated locally by the Client. Reason 440: Driver Failure. Rebooting the machine does not help, trying all other solution does not help. After some fumbling, painful, repetitive, trial and error, finally I found the way to do it right. You can do like-wise by following the steps below, to ensure that your Cisco VPN Client continues to work well after migrating to Windows 10 OS. If you are lazy or too busy to find the software listed below in the instructions, you can download the all-in-1 package from here for your convenience hosted locally : version 3, 2018 , version 2, 2015-2017. As the usual disclaimer goes, I will not be held responsible if anything goes wrong with your computer or hardware or software, or causes you to suffer any loss of any sorts, so do backup your data if you want to go ahead. Ok, now that we have got the disclaimer out of the way… Gentle Reminder 1: Please uninstall any previously installed Cisco VPN Client software or DNE updates that you may have installed prior to this guide. This ensures a clean configuration for the guide to work properly. Prep Step 1: Disable Your Secure Boot Only if applicable. If your secure boot is NOT enabled by default, then skip this! While secure boot is a useful security standard developed by members of the PC industry to help make sure that your PC boots using only software that is trusted by the PC manufacturer, sometimes it gives us more problems than convenience. Many older 32-bit x86 drivers are not signed, because kernel-mode driver signing is a recent requirement for Secure Boot. Therefore, in this case, the older Cisco VPN software is not compatible with secure boot, and means that you will have to disable secure boot on your PC. This may be escalating problem if you are using BitLocker, and it may require you to get a recovery key to boot in non-secure-boot mode. Well, at least it was necessary on my Windows machine. You can often access this menu by pressing a key during the bootup sequence, such as F1, F2, F12, or Esc. This option is usually in either the Security tab, the Boot tab, or the Authentication tab. Note: In some cases, you may need to change other settings in the firmware, such as enabling a Compatibility Support Module CSM to support legacy BIOS operating systems. To use a CSM, you may also need to reformat the hard drive using the Master Boot Record MBR format, and then reinstall Windows. For more info, see Windows Setup: Installing using the MBR or GPT partition style. On some machines, you may see a watermark on the desktop alerting you that Secure Boot is not configured correctly. Make sure any versions you might have installed are cleanly uninstalled with all directories removed just to be on the safe side. Clean Step 3: Install and run the DNE fix from Citrix DNE stands for Deterministic Network Enhancer. This actually helps make sure that the DNE is fixed and cleaned up, in preparation for the Cisco VPN client software. First, go to: to get the file. Install Step 4: Install the Sonic VPN and then Cisco VPN Client Software Install the Sonic VPN software which will be able to install the right version of the DNE. The installer can be found in the All-in-1 download link above. Sonic VPN will ensure the right DNE is installed. This will increase the success factor of your installation. Some users have experience problem with running the. Follow the usual installation steps thereafter. Tweak Step 5: Make changes to the registry If you do not make changes to the registry, you are likely receive the following error: Secure VPN Connection terminated locally by the Client. Reason 442: Failed to enable Virtual Adapter. Open Registry editor regedit in Run prompt 2. If you experience DNS lookup problems after the VPN is connected, do this: set IP metric for the Cisco VPN to 1, and set the IP metric for Local LAN connection to 50. Problem 2 You still experience 442 error even after changing the registry string You can try to disable Internet Connection Sharing ICS — tip from Phil Raymond. Problem 3 You experience Error 433 after following the instructions: Secure VPN Connection terminated locally by the Client. Reason 433: Reason not specified by peer. The likely reason was apparently due to the DNE LightWeight Filter network client not being properly installed by the Cisco Systems VPN installer, or something is wrong with DNE. E Reboot your computer again. F Install the Sonic VPN software which will be able to install the right version of the DNE. G Reboot your computer. H Reinstall the Cisco VPN Client software again. You do not need to uninstall the Sonic VPN software from step G. EXE file, to improve the odds of success. I Perform registry fix Step 5 if not fixed yet.
