Hi All,

This question was originally posted on Jan 20, 2020 at https://forums.openvpn.net/viewtopic.php?f=6&t=29484 but got no answer

Windows 10 Pro, 1909 x64
openvpn-install-2.4.8-Win10.exe

Under 1903, I was able to easily establish a network bridge. Well 1909 occurred and the bridge could no longer get a DHCP address. Breaking the bridge and re-establishing it did not help. Removing, rebooting, and reinstalling OpenVPN did not help either. I keep getting

    An unexpected error when configuring the network bridge

And I have three other identical computer -- hardware and software -- that are working perfectly.

GGGG RRRRRRR !!!!!

Any word of wisdom?

Many thanks,

Hi,

The issue might have occurred due to certain files in the WMI repository which is blocking you to create network bridge.

1. Click on Start; in the start search type cmd. 

2. Right click on cmd.exe and run as administrator.

3. Execute the following commands.
   net stop winmgmt
   cd /d %windir%\system32\wbem
   ren repository repository.old
   net start winmgmt

4. It may take a minute or so to complete while WMI rebuilds the database.

Restart the computer and then try creating a network bridge again.

Regards,

No MAC Bridge Miniport.  The arrow are for the two I am trying to bridge.  They are not bridged at the moment.
