Yes, that’s true, today I decided to write something about some two typical errors that we see on Dcom and most of the times drives some of us a little bit mad.
Yes, that’s right DCOPM is still a thing in our bright days of could computing and IoT.

So, some of the most popular errors on the DCOM World are the below (they usually also like to hang out together), see how to tackle them.

DCOM Event ID 10010
Description:
The server {AppGUID} did not register with DCOM within the required timeout.

Typical Causes

1. NTFS permissions have been locked down.
2. Dll’s have become unregistered (check to see if they are corrupted).
3. The service failed to start or is at either starting/Stopping state (hung).
4. An application tries to restart the service repeatedly.
5. Bug in the 3rd party or custom application.
6. RPC service has “Allow Service to Interact with Desktop” checked.
7. A dependent service starts before the service throwing the error.
8. Permission of application is set incorrectly.

Usual Resolution

1. Check the Check NTFS permissions (DCOM) .
2. With the AppGUID, find what application it is and try Re-registering exe’s (DCOM)
3. Stop and try restarting the service.
4. Disable 3rd party services and startup items, go thru the process of elimination.
5. Check for an update from the software vendor.
6. Uncheck the “Allow Service to Interact with Desktop” within the RPC service and reboot.
