After an enjoyable weekend I walked into work this morning, opened up Chrome, navigated to my client’s production Tridion as normal – WHAM – COM Exception:

Retrieving the COM class factory for component with CLSID
{9926D1CF-F158-418F-A9A2-B653B497D982} failed due to the following
error: 80004005 Unspecified error (Exception from HRESULT: 0x80004005
(E_FAIL)).

This appears to be the CM_TOM.dll – problem is I’ve restarted COM servers, IIS etc. but nothing seems to work.

I’m about to restart the machine but wondered if anyone here had come across this before?

    OK, for future reference – resolved this via the following steps:

    • Open the Global Policy Editor snap-in.
    • Go to Computer Configuration >
      Administrative Templates > System > UserProfiles.
    • Double-click ‘Do
      not forcefully unload the user registry at user logoff’
    • SelectcEnabled and click OK.
    • Reboot the server
