Event Viewer shows lots of warnings with DCOM issues

[atomich63]

Event Viewer has lots of warnings and this one shows up repeatedly.  I have tried to fix it many times, but many of the options are either grayed out, not listed, or don't work. I know this is a Windows problem but am posting here also to try to get it fixed without doing yet another clean install.

Here is the description shown in Event Viewer, Windows Logs, System:

The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{C2F03A33-21F5-47FA-B4BB-156362A2F239}
and APPID
{316CDED5-E4AE-4B15-9113-7055D84DCC97}
to the user HPLT15\Michael SID (S-1-5-21-3964592820-1767007959-1107817282-1001) from address LocalHost (Using LRPC) running in the application container Microsoft.Windows.ShellExperienceHost_10.0.19041.4239_neutral_neutral_cw5n1h2txyewy SID (S-1-15-2-155514346-2573954481-755741238-1654018636-1233331829-3075935687-2861478708). This security permission can be modified using the Component Services administrative tool.

In regedit, I get access denied messages, and I can't change the DCOM permissions on it. 

Are these warnings in Event Viewer something I can ignore?

Hi @atomich63,

Welcome to the HP Support Community. 

I'd be glad to help you! 

That is an excellent description and a great diagnosis. It is greatly appreciated.            

DCOM (Distributed Component Object Model) warnings in Event Viewer are a common occurrence and can be tricky to assess. Generally, they indicate that an application or service attempted to communicate with another application or service and failed, typically due to permissions issues. However, they are not always critical and may not affect your system’s performance.

Here’s a breakdown to help you understand if these DCOM warnings on your HP DV6-7214NR can be safely ignored or require attention:

1. Common Causes of DCOM Errors:

• Permission Issues: Many DCOM errors or warnings are caused by misconfigured permissions between services.
• Disabled Services: Sometimes, DCOM warnings appear when Windows attempts to contact a service that is disabled or not running.
• Network Connectivity: If your computer is part of a network, DCOM warnings could be related to network services that failed to respond or were unavailable.

2. Should You Ignore Them?

In many cases, DCOM warnings can be safely ignored if:

• You don’t notice any performance issues: If your system is running smoothly without crashes, slowdowns, or application failures, these warnings are often harmless.
• The warnings are not frequent: Occasional DCOM warnings that don’t appear in rapid succession may not indicate a serious problem.
• No specific applications are failing: If there are no apps or services failing to work due to the DCOM issues, you can likely ignore them.

3. When to Investigate Further:

You may want to investigate or fix the DCOM warnings if:

• You are experiencing system or application crashes: If you notice performance issues, such as slowdowns, freezes, or application failures, it’s worth investigating the warnings.
• There are multiple recurring warnings: If you see the same DCOM warnings frequently (multiple times a day), it could indicate a persistent problem with a service or permission setting that should be addressed.
• Certain applications are not working properly: If you notice that certain apps or services are not behaving as expected, the DCOM warnings may be related.

4. How to Troubleshoot or Fix DCOM Warnings:

• Identify the source: Check the Event Viewer log for more details on which service or application is causing the DCOM warning. Usually, the Event Viewer will show the CLSID or APPID related to the issue.
• Modify permissions: In some cases, the warning is caused by permission issues with DCOM services. You can modify DCOM permissions using dcomcnfg (Component Services), but this requires careful changes.
• Check for updates: Make sure your Windows installation and all drivers are up to date. DCOM warnings can sometimes occur due to outdated software.

Steps to Access Event Viewer:

1. Press Win + X and select Event Viewer.
2. Navigate to Windows Logs > System.
3. Look for DCOM errors (Event ID 10016 is common for DCOM errors).
4. Examine the error details, which will include information about the service or process causing the issue.

In most cases, DCOM warnings in the Event Viewer can be ignored if your system is functioning normally. If they are persistent or accompanied by system performance problems, it may be worth investigating further by adjusting DCOM permissions or troubleshooting the affected service. However, unless they are directly causing issues, you don’t need to worry about them.
