For the adapter you were using VPN, remove the VPN "adapter" and protocol used by the VPN software. Then add it back to the adapter so it sits on top of the protocol stack rather than getting squeezed out by the newly added Siemens Profinet protocol stack.

smopi Member Joined: 9/30/2019 Last visit: 8/11/2022 Posts: 1 Rating: (0)	Hey there, using SinemaRC to connect to an OpenController 1505. Unfortunately i couldn't connect after installing TIA V17, because ending up in bluescreen. ndis.sys After unchecking "SIMATIC Industrial Ethernet (ISO)" my Remote Desktop connection works again but ther is no PLC visible in TIA anymore. Same problem in V16. After reactivating "SIMATIC Industrial Ethernet (ISO)" the remote PLC is visible again but immediately after estabishing connection it ends up with bluescreen again. Are there any further suggestions or is ther an other workaround available already? Thanks in advance.

themis.chatzis Experienced Member Joined: 3/27/2015 Last visit: 11/13/2023 Posts: 2 Rating: (0)	Not yet confirmed it 100% but i believe that this error is generated only when you are using ISO (L2) protocol with a non-signed or non-trusted certificate. Tested it in both NDIS 6.0 (fortinet ssl - proprietary driver) and 6.30 (watchguard ssl - tap driver) drivers with the same result. Private firewall with the default certificate and without a locally installed certificate for the user gives a blue screen. Azure gateway, eWON eCatcher (tap driver - same version with watchguard) and others cloud based gateways with the same functionality are working fine with SSL VPN but they have installed locally the trusted certificate.

Stano40 Experienced Member Joined: 10/22/2014 Last visit: 9/1/2025 Posts: 3 Rating: (0)	You won´t be able to use ISO-on-TCP communication protocol (correct me If I am wrong). I also was getting BSOD not only with OpenVPN but also using ordinary IPv4 communication. I also solved this issue by turning off Simatic Industrial Ethernet (ISO) at my all network cards, but I think, that this solves this issue only temporarily, Siemens should fix this ASAP in next update or hotfix.

AutoGen_6916347 Member Joined: 10/9/2020 Last visit: 4/29/2022 Posts: 1 Rating: (0)	Workaround... It works... While connecting to a VPN like - Pulse secure, as soon as the Network adapter for Pulse secure is available in network connections, put your laptop/ computer on Airplane mode using shortcut keys. This will provide you some more time to open properties for the VPN - Pules secure adapter and to deactivate the "SIMATIC Industrial Ethernet (ISO)" protocol from the pulse secure network properties. Good luck.. Rahul C Attachment SIMATIC_Industrial_Ethernet(ISO).JPG (843 Downloads)

sancruz Gold Expert Joined: 3/11/2019 Last visit: 9/1/2025 Posts: 1653 Rating: (322)	Hi EloyJSB, as already mentoined earlier in this post, this was fixed with update 2 for V17 (in the meantime update 5 is available). It is not necessary to deactivate the service/protocol. Just install the latest update. If STEP 7 classic V5.7 is installed in parallel on the same system, also install latest hotfix for V5.7. Updates for STEP 7 V17, S7-PLCSIM V17 and WinCC V17 Download Hotfix 4 STEP 7 V5.7 / STEP 7 Professional 2021 regards sancruz

My setup was OpenVPN running in VMWare Player The network adapter was called TAP-Windows V9 for OpenVPN Connect. I watched Network Connections and found which one connected as I started my OVPN connection and then turned SIMATIC Industrial Ethernet (ISO) off for that connnection.
