Body
Overview
An issue has been identified with certain installations of the Ivanti Secure Access Desktop client on Windows 10 workstations that significantly impact network performance. The issue does not impact all users; it appears to be limited to specific network adapters. The issue has been identified to impact some wireless/wi-fi adapters but may express itself on some wired adapters as well.
The symptoms of this issue are:
- While connected to the UTK VPN gateway (access.utk.edu) with the Ivanti Secure Access Desktop Client (versions 9.0.x and 9.1.x) users will see significantly poor network performance to non-VPN destination services (services hosted outside the University of Tennessee network).
- Examples of these services are, but not limited to, Office 365, Cayuse Research Support, Canvas, and others.
Instructions
To resolve this issue:
- Disconnect/close any connections to the UTK VPN service.
- From the Start Menu search box, search for "ncpa.cpl" (Network Connections Control Panel).
- Identify your currently used network adapter in the Network Connections Control Panel. Most users will see Ethernet, Wifi, or some variation thereof.
- Right-click on the network adapter icon and select Properties.
- From the list, uncheck the checkbox for Juniper Network Service.
- Connect with Ivanti Secure Access Desktop Client. (This is necessary to change the virtual adapter settings. If the Ivanti Secure Access tunnel is not connected, the virtual adapter does not appear in the Network Connections.)
- From the Network Connections, select Ivanti Secure Access virtual adapter.
- Right-click the adapter and select Properties
- From the list, uncheck the checkbox for Juniper Network Service & Click OK.
