Windows Management Instrumentation Problem causes the Virtual Adapter was not Set up Correctly Due to a Delay Error; GP App reports "The virtual adapter was not set up correctly due to a delay"

GP App reports an error of "The virtual adapter was not set up correctly due to a delay. GlobalProtect will try again soon. If the issue persists, try restarting your system." after the user enters his credentials.

 

• PAN-OS Firewall configured with GlobalProtect Portal and Gateway
• GlobalProtect App
• Windows OS

The error "The virtual adapter was not set up correctly due to a delay. GlobalProtect will try again soon. If the issue persists, try restarting your system" is a generic error where PANG Virtual Adapter is not setup correctly. There could be multiple root causes.

One of the root causes is a Windows system with corrupted Windows Management Instrumentation (WMI) components. 

To confirm the WMI corruption, we can run the following commands in Windows CMD with administrative access to collect system name, domain, and info:

wmic computersystem get name
wmic computersystem get domain
systeminfo

If the output of these commands is "ERROR: Invalid class" or "ERROR: Description = Invalid namespace", it means that Windows WMI has a problem and the GP client is not able to access the virtual interface that is needed to complete tunnel creation.

Please note that the problem is in the Windows WMI component and not with the GP App itself.  There are different ways to fix the Windows WMI, please consult with Microsoft or engage your IT.

One of the ways to rebuild WMI is by following the steps below; details are in the Microsoft article: How to fix "Invalid Class" in Powershell
