We encounter the same issue (Win7 Pro x64) after a previous unistall of Pulse Secure.
BFE is running
MaxNumFilters registry value is set to 8 (we tryed to change but without results)
On device manager we found: Juniper Networks Virtual Adapter Manager (with yellow exclamation point and error code 39)
but we do not found the: Juniper Virtual !!Adapter!! listed as network adapters
This could be the issue?
We are facing the same issue on Win 7 Pro x64 after reinstalling Pulse Secure (previous uninstall due to other reasons).
BFE is ok
MaxNumFilters registry is set to value 8 (we tryed even with 14 but the issue persists)
On device manager we found: juniper networks virtual adapter manager (with yellow exclamation point and error code 39)
but we don't found: juniper adapter (show hidden devices active)
This could be the cause?
Could you give us some hints in order to restore?
