What is the “Unable to Start a DCOM Server” Error?
The “Unable to Start a DCOM Server” error is a Windows-specific error that typically occurs when a user is trying to launch a COM+ application. This error can also occur if the user is trying to launch a DCOM server that is either not registered or is not running.
There are a few different ways to fix this error, but the most common solution is to simply register the DCOM server that is causing the error. To do this, you will need to use the Microsoft Component Object Model (COM) Registration tool (Regsvr32.exe). You can find this tool in the Windows\System32 directory.
Once you have registered the DCOM server, you should be able to launch the COM+ application or DCOM server without any problems.
How to Fix the “Unable to Start a DCOM Server” Error
If you receive the error message “Unable to start a DCOM Server. Error 5,” it means that the Distributed Component Object Model (DCOM) server could not be started because the required service is not running. This error can occur for a number of reasons, but the most common cause is that the DCOM service is not properly configured.
There are a few things you can do to fix this error. First, check to see if the DCOM service is running. To do this, open the Services control panel and look for the Distributed Component Object Model service. If the service is not running, start it and set it to automatically start in the future.
Next, check the DCOM configuration settings. To do this, open the DCOM Config tool from the Component Services control panel. Find the program that is generating the error and double-click it to open its properties. In the properties dialog, go to the Security tab and make sure that the correct permissions are set for the service.
If you are still having problems, you may need to repair or reinstall the DCOM service. To do this, open the Registry Editor and navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole
Right-click the Ole key and select Permissions. Add the user account that is having problems and give it full control of the key. Once you have done this, restart the computer and try starting the DCOM server again.
Conclusion
