Cannot run Fiddler in WS 2012 - Unable to use NetIsoEnumAppContainers to get AppContainer list. WinConfig button cannot be run

[Veljko]

Hi,

 

I have big issue with fiddler in Windows Server 2012 and IE 11.

When I run fiddler, it offers me WinConfig option to click from top left corner but it throws errors:

Unable to use NetIsoEnumAppContainers to get AppContainer list.
ErrorCode: 0x0
Attempting manual registry crawl; some information will be unavailable.

I am receiving error: Failed to get AppContainer info   as WinConfig action.

 

My Windows Firewall Service in services.msc is started and windows firewalls for  domain, public and private network are off.

I read that for someone starting the Windows Firewall Service resolved the issue but it is already started on my server.

 

I read on internet:

What else should I do how to resolve it?

Thanks

Hi,

Well, actually you should be stopping the Windows Firewall Service. Rather unfortunately there is not much else you can do. 

Please, have a look at this - http://www.telerik.com/forums/fiddler-not-working-with-windows-store-apps-on-windows-8-1#iYIQNbExAUaJCCNnnm6ITQ

Hi,

 

I came across exactly the same issue on W2012R2. But in my case even AppContainer Loopback utility shows empty list and complains about firewall not running whereas it's exactly running. What I'm doing wrong ? How to have it working?
