Windows 10: COM error with SIHOST.EXE

Hi,

I'm regularly getting in the Event Viewer the following error message related to SIHOST.EXE :

The machine wide limit settings do not grant Local access permission to the COM Server application c:\windows\system32\sihost.exe with APPID
Unavailable to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

I have checked the permissions in DCOMCNFG and the defaults settings grant LOCAL SERVER all the necessary rights.

According to this message, SIHOST.EXE is a COM server but I don't see any declaration related to this server in the registry (no APPID, no CLSID,...).

Any idea ?

Thanks in advance.

:)

COM error with SIHOST

Actually, I get this error twice in a row :

First with event ID 18210 :

The application-specific permission settings do not grant Local access permission to the COM Server application c:\windows\system32\sihost.exe with APPID


Unavailable

to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). The application set this security permission programmatically; to modify this security permission
contact the application vendor.

then with event ID 18211 :

The machine wide limit settings do not grant Local access permission to the COM Server application c:\windows\system32\sihost.exe with APPID


Unavailable

to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

The source is COMRuntime in both cases.
