Problems with DCOM / WMI - default trustee removed

[MJ Wiechowski]

Hi,
I have been loking for a solution everywhere on the net but I found more
unanswered questions than solutions.

WMIDiags.vbs give me a numner of errors that look like this:

DCOM security for 'Microsoft WBEM UnSecured Apartment' (Launch & Activation
Permissions)................... MODIFIED
!! ERROR: Default trustee 'BUILTIN\ADMINISTRATORS' has been REMOVED!
** - REMOVED ACE:
** ACEType: &h0
** ACCESS_ALLOWED_ACE_TYPE
** ACEFlags: &h0
** ACEMask: &h1
** DCOM_RIGHT_EXECUTE
**
=> The REMOVED ACE was part of the DEFAULT setup for the trustee.
** Removing default security will cause some operations to fail!
** It is possible to fix this issue by editing the security descriptor
and adding the ACE.
** For DCOM objects, this can be done with 'DCOMCNFG.EXE'.

Ok, I fired up DCOMCNFG.EXE, went to Component Services - Computers - My
computer - DCOM Config

I did not find any entry for 'Microsoft WBEM UnSecured Apartment' there!

What is the solution, not counting a total reinstallation of Windows?

Kind regards

I would like to add that I performed a total reinstallation of WMI, as
described elsewhere.
Still, there are errors on "removed trustees" and also two DLLs that are not
properly registered (I DID register them!): fastprox.dll and wbemprox.dll.
