Windows 7: Event ID 10016 -- DCOM permissions error

Thanks John
I guess you mean some installation went wrong?
How would I set permissions on a CLSID that doesn't exist?

I am running windows 7 64 bit with the same problems and same error messages. I also have the same wireless printer (brother) but connected by ethernet hard wired cable. I cannot get the error to go away with all the suggested remedies. Does anyone have any further information on this as microsoft has been no help?

ive had a friend try everything listed in this thread and nothing worked im still getting this exact same error. has anyone been able to completely fix this issue?

Not without the actual 10016 error text - the CLSID in it will track back to an AppID, which will denote which COM object is failing. Given there can be hundreds of COM objects on a machine, and a COM object alone can have multiple AppIDs, it's kinda important to get the actual error message text .

This thread became quite lengthy and information on how to solve distributed... I tried to make a cookbook solution for my (as it seems not so rare) entry in the Eventviewer:

---
The solution of this problem is described by Event 10016 may be logged in the System log on a computer that is running Windows XP Professional x64 Edition. However this solution can not be applied as even the 'Administrator' does not have rights to change the Launch rights!

I searched the registry to find:
- CLSID {C97FCC79-E628-407D-AE68-A06AD6D8B4D1}
and
- APPID {344ED43D-D086-4961-86A6-1106F4ACAD9B}
both resolve to 'IPBusEnum'!

To be able to apply the MS-Patch you need to:
1) Take Ownership (right click on key) off the following objects (make sure to check 'Replace owner on subcontainers and ojects' as well) :
- HKLM\Software\Classes\AppID\{344ED43D-D086-4961-86A6-1106F4ACAD9B}
and
- HKLM\Software\Classes\CLSID\{C97FCC79-E628-407D-AE68-A06AD6D8B4D1}

2) Set Permissions (right click on key). Grant 'SYSTEM' and 'Administratos' 'Full Control' for:
- HKLM\Software\Classes\AppID\{344ED43D-D086-4961-86A6-1106F4ACAD9B}
and
- HKLM\Software\Classes\CLSID\{C97FCC79-E628-407D-AE68-A06AD6D8B4D1}

Note:
I did the above for
- HKEY_CLASSES_ROOT\CLSID\{C97FCC79-E628-407D-AE68-A06AD6D8B4D1}
as well. But I do think there was no need for this....

Now go back to Event 10016 may be logged in the System log on a computer that is running Windows XP Professional x64 Edition and grant SYSTEM and LOCAL SERVICE all Permissions!

In case KB899965 vanishes:
- Run 'dcomcnfg'
- In Component Services, double-click Component Services, double-click Computers, double-click My Computer, and then click DCOM Config.
- Locate 'IPBusEnum' in the right pane and use 'Properties' --> 'Security' --> Launch and Activation Permissions area, click Customize, and then click Edit.
- If not exisiting add SYSTEM and LOCAL SERVICE
- check under 'Permissions for ... ' all 'Allow' boxes!
- go back to 'Security'. Click 'Apply'

This is aggravating the piss out of me. Randomly my computer will just restart or power off totally. When I go o the event viewer I can track it down to this error specifically by timing. This is basically the only error I am getting in the event viewer and it's the same error that I find after I start the system back up.

I have tried all the suggestions here and on the tech net site. It's getting very aggravating because it's not a timed thing, it's not a heat thing. It's not anything that I can seem to pin down other than this one error which many say I can ignore. Well I cannot ignore it as it is shutting me down randomly. Sometimes I will be on for 5 hours straight before it occurs, sometimes I am not on for 10 minutes and it happens.

I will attach the DXDIAG Reports and perhaps someone can figure out WTF is really going on here. Keep in mind that I do not get a blue screen, an error message pop up or even a warning that it's going to happen. Everything is going along just peachy and then snap reset. This is not virus related in anyways as I have run scans with the following. Spyware Doctor W/Antivirus, SuperAntiSpyware, MalwareBytes, Eset Business Online Scanner. In addition this has been an issue through several clean installs of Windows 7 on this machine. In other words I have installed Windows about 6 different times installed the drivers and windows updates and this problem is still recurring.

So I have to believe that something installed is randomly trying to access this DCOM service and whatever it is seems to cause total failure of the OS kernal all at once when it happens.

Someone please help!!! this is making me insane as I have been researching this for months already with no resolution in site.

Thank You

Hey Paul - welcome to SF. You might want to put this into it's own thread though, as it has nothing to do with this one and is really hard to find. You'll probably get more help if you create a new thread for this.

PB Solved by me under Windows Seven 32 bits.
Exactly the same PB.
After I granted the FULL rights to these two keys, I still received this 100016 error message.
The last thing I did is:
net localgroup Administrators "NT Authority\LocalService" /add

And now , the PB has gone.

Youpiiiiii, thanks guys.

I always disable DCom, never need it since Win98 days.

Can you give me the steps to do this?
