The issue is with Anti-Virus NDIS and other miniport driver and its binding to the Juniper Network Connect Virtual Adapter.
In Control Panel > Device Manager > Network Adapter
(click View > Show All Hidden Devices
), it will display two more NC drivers such as Juniper Network Connect Virtual Adapter and the other variant of Juniper Virtual Adapter driver (usually shown as Juniper Network Connect Virtual Adapter - Packet Scheduler Miniport or <some manufacture> NDIS).
This causes several issues as the Anti-Virus NDIS Filter or Miniport are intermediate-drivers that bind to the primary NDIS (such as Juniper NC driver). The established network connections might be broken during the application installation, as the intermediate driver is not properly passing the packet to Juniper Network Connect Virtual Adapter; so the user might receive the 23790, 23791, or 23712 error or no traffic is properly passed through.
