DCOM error Event ID 10016

I am getting DCOM errors every 5 minutes with the following error message:It appears the error is in IIS, that's why I posted here. If it is not, let me know and I'll post in OS section.

Error: DCOM Event IS 10016

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{6376B42B-4F1C-11D5-8CA9-E6E4B0453330}
 to the user MCOL6B\IUSR_MCOL6B SID (S-1-5-21-1000164821-1436205007-2007182233-1003).  This security permission can be modified using the Component Services administrative tool.


In clicking on the Microsoft link and followed the directions in the Component Services Admin tool, but I was stumped in Para 6 by the "friendly name" reference. I have no way to know what the friendly name is.

Help would be appreciated.

Hello Abs:

I do not have SMS and the exchange soution link you provided is also not my problem here.

It looks like your detailed solution at the beginning was copy/pasted from the OS solution. It looks like you also copied over the other CLSIDs which aren't germaine for my problem :).

I did follow your suggestions at the first post. However what is very strange is that I could not find my specific CLSID number referred to in the Error message (10016) in the component services details list . There is also another DCOM error with another CLSID and it also I could not find in the Components Details list. How can I get error messages on component permissions if they do not appear in the components list???

As an aside, I have gone through the Microsoft articles #812614 and the Article #332097 and made sure all IIS permissions are correct.

Help would be appreciated. Thanks

Hi Abs_jaipur,

I have also had the same issue but only for a short period, exchange got locked and a server reboot cleared this issue. We now do not have any DCOM issues (at present) however when I tried to follow your 11 steps I found that I did not have {BA126AD1-2166-11D1-B1D0-00805FC1270E} listed in Component Services/Computers/My Computer/DCOM Config. {BA126AD1-2166-11D1-B1D0-00805FC1270E} is definatly what is shown on the error in event viewer.

Should I be concerned?

Cheers
Peter
I too have the {BAE126.... exact same as Peter wrote. It is not listed in the Component Services/Computers/My Computer/DCOM Config section. I have Windows 2003 with SP2 running SQL server and nothing else.  My DCOM errors are 1x per day for a minute, or every few days...not multiple times each day.  Any ideas how to resolve as the fixes above did not seem to apply.  I also do not have "NETWORK SERVICES" as a selection when I try to add it as suggested in some of the posts earlier in this topic. Appreciate any suggestions.
Tnx

Fix DCOM and NAP error using registry script
I have experienced the same annoying Event ID 10016 regarding local start permission and this is how I solved it creating a registry-file which is launched from a batch file. (Some choices may be slightly different, because I have a Norwegian version of Windows.)
1. Locate the APP ID by searching registry
- Copy CLSID from the event log      {24FF4FDC-1D9F-4195-8C79-0DA39248FF48}
- Copy CLSID into the search dialog of registry
- Search until you find a value named AppID
2. Locate the service
- Copy the data into the search dialog
- Search for the data until you find a value called LaunchPermission
you should see the standard value NAP Agent Service
3. Create a registry backup
- Backup the value via File-Export
4. Change the security setting and create a new reg-file
- Start dcomcnfg.exe
- Navigate to Component services-computers-my computer-DCOM configuration
- Right click NAP Agent service
- click the security tab
- click Start and activation permissions - Custom
- click Edit
- Choose System and tick Local startup
- Close dcomcnfg.exe
- Backup registry (dcomcnfg.exe should be closed first), call the file FixNap.reg
5. Batchfile (one line)
- regedit /s FixNap.reg

This is it! Now you have a batch file which you can use to automate this patch.
Good Luck  :)
