I built a really simple UserControl using the SocialShare control, just creating by creating a .ascx and registering the Telerik type.
It works fine as a widget on a Sitefinity website, but is causing DCom 10016 errors to be thrown.
The webserver was complaining that the account NetworkServices didn't have permissions to activate the specified application, and although it was easy enough to grant permissions (dcomcnfg) I was dubious about why I should need to do that.
However, I am also getting a similar DCom error being thrown on the client if I am using IE11 and need to use the developer tools to debug IE.
This is obviously a bit more disconcerting, as there shouldn't be a need to grant permissions for this type of scenario.
What am I doing wrong?
