A very common problem in the SBS server is the Error 10016. This error occurs as a result of incorrect rights on the service IIS WAMREG admin. This issue is not difficult to solve, but you must correct the registry key and the DCOM object:
- Run regedit.exe and locate HKEY_CLASSES_ROOTAppID{61738644-F196-11D0-9953-00C04FD919C1} key
- Right click on the key and select Permissions and then Advanced
- The first thing to do is to give the ownership to the Administrators group in the Owner tab
- After this, you have to switch to the Permissions tab and add to the Administrators group full control rights. DO NOT CHANGE OTHER PERMISSIONS!
- Now you have to open the Component service (dcomcnfg.exe) and navigate to the Console Root > Component services > My Computer > DCOM Config. On this location you will find the IIS WAMREG admin component. Right click on it and select Properties.
- On the Security tab, under Launch and Activation Permissions,select Edit
- Here you must enable the Local Activation right to the SharePoint Farm Account
- Close all windows with OK.
