Internet Connectivity lost on installing ndis filter in presence of HIPS 8.0
we are planning to deploy/develop ndis filter driver using the sample [Windows NDIS 6.0 Filter Driver sample in C++ for Visual Studio 2013] . As soon i install this ndis filter driver internet connectivity is lost. And I am getting Activity log on HIPS as "Block All Traffic" . Only way to restore internet connectivity is reboot or we need to disconnect and connect back LAN cable.
This issue is happening only in presence of HIPS 8. on uninstalling the HIPS 8.0 this issue is not reproduced.

From your thread it appear you want to "deploy/develop ndis filter driver"? So this is more a developer question and not a typical user question.
I don't know much developing of NDIS, however, HIPS is sensitive to other NDIS filters and might detect your driver as an intrusion or simply something is wrong. Please make sure that your new filter is not taking a higher place than HIPS NDIS driver, i.e here: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network.
