Fix for SharePoint DCOM 10016 error on Windows Server 2008 R2

In the past this error could be solved by giving the mentioned accounts the “Local Launch” and “Local Activation” permissions to the IIS WAMREG admin service through Component Services.

On Windows Server 2008 R2 this is quite different. The property dialog is all disabled due to permission restrictions. It doesn’t matter if you are logged in as an administrator or using elevated privileges

Search in the registry for this key “{61738644-F196-11D0-9953-00C04FD919C1}” and change ownership by doing this:

1. Click Advanced in the Permissions dialog of this key and select the Owner tab
2. Change the owner of the key to the administrators group
3. Set full control to the administrators group

Now restart the Component Services and you’re ready to set the correct permissions.
