I have occasionally gotten either of the following errors in my BizTalk Administration console, and am then unable to refresh the BizTalk Group Hub:
"An instance of the FreeThreadedDOMDocument class cannot be created" "Failed to create a CLSID_BizTalkPropertyBagFactory"
I still don’t know why it happens, but the solution is simple: Restart the Windows WMI Service.
With thanks to this blog article.
