open regedit and right click on HKEY_CLASSES_ROOT select find and search for that clsid (in my case D9B257A6-C7FC-4B76-9824-599466B69D3B and AD65A69D-3831-40D7-9629-9B0B50A93843)

Note the the name of the clsid (im my case sms host agent).

Open Component Services. Got oStart –> Control Panel –> Administrative Tools –> Components Services. Expand the Component Services branch then expand Computers, My Computer and DCOM Config. Right-click on “sms agent host” (my case) and click Properties. Click on the Security tab and under “Launch and Activation Permissions” select “edit” and add user Local Service (Local lunch). Click OK, close the Component Services window. The error should vanish.

Do a restart (its a feature of Ms Windows)
