How to Restore Network Connectivity due to DNS Settings Issues on Physical Adapter and FQDN Split Tunneling is configured?

This article describes a scenario where domain name server (DNS) settings are not properly restored on the physical adapter when using FQDN Split Tunneling or Device Only DNS is enabled.
Problem or Goal
End users lose their network connectivity during a tunneled connection.  End user may notice that all DNS resolution will fail, but able to connect to resources via IP Address.
Cause
This issue is caused due to DNS settings not being restored on physical adapters (Ethernet/Wireless) when using FQDN split tunneling. This issue may occur during wake up after the machine was put to sleep/hibernate and restart/reboot scenarios.
 
Note: Applicable only to Pulse Desktop Client (Windows)
Solution

To resolve this issue, please upgrade to Pulse Desktop Client 9.1R7.1 and above.

To workaround this issue, use IP-based split tunneling instead of FQDN split tunneling.

Note:
  1. Sleep/hibernate scenarios are fixed only in Pulse Desktop Client 9.1R6 and above.
  2. Sleep/hibernate and Reboot/Restart scenarios are fixed in Pulse Desktop Client 9.1R7.1 and above.
