It was amazing to get this issue. Today morning I opened my BizTalk admin console and got this issue. I don’t know what was happened. Yesterday It was working fine and perfectly.
An Internal Failure occurs for unknown reason (WinMgmt)
I have got some weird reason for this. My machine has run window updates and due to these new updated patches up I am getting this issue.
Root cause: July, 2018 Microsoft Security Updates cause errors on the BizTalk Administration Console: An internal failure occurred for unknown reasons (WinMgmt)
After applying this month’s security patches, we get the above errors in the BizTalk Admin Console when either refreshing the Group Overview or trying to view any of the Platform Settings on BizTalk Servers.
Solution: till now no solution is yet to figure out from Microsoft. You need to just uninstall the window updates of last day. Then restart the system and it starts working. Bingo😊
Location: We need to uninstall this update via Start->Control Panel-> Program and features-> View Install Updates
Below is list of Windows updates you may need to uninstall. Few of them available and sometimes few are not available on your machine.
- BizTalk Server 2016: KB4338605, KB4338613, KB4338424, and KB4338419
