Perhaps you've experienced the scenario where you hit the F5 key on the Group Overview in the BizTalk Admin console and instead of seeing your message queues, you see instead the very ugly () message:
Failed to create a CLSID_BizTalkPropertyBagFactory COM component installed
with a BizTalk server. A dynamic link library (DLL) initialization routine
Go to the event viewer and look for any COM/COM+ errors under applications. Chances are you will see a conflict with WMI services--perhaps a threading error. Since the SSO, BizTalk Admin Console, SCOM...(even event viewer) use WMI for the MMC console, one of the DLLs for WMI may have become unavailable. If WMI is not available, or the WMI service has crashed, the console for the BizTalk Admin can fail with this error message as its swan song ().
Aaron Tiensivu's blog offers a way to isolate WMI issues on svchost:
There are 2 solutions that I know of, 1 radical and 1 less so...
- restart the server [waaay radical, but effective]
- restart the WMI windows service
