Event ID 10016 logged on Windows SBS 2008

What:

Microsoft Windows Small Business Server 2008

Problem:

Event ID 10016 from DistributedCOM

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {61738644-F196-11D0-9953-00C04FD919C1} to the user NT AUTHORITY\NETWORK SERVICE SID (S-1-5-20) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

Solution:

GUID 61738644-F196-11D0-9953-00C04FD919C1 corresponds to the service IIS WAMREG Admin Service.

1. Click Start then Run and type "dcomcnfg". Click OK.
2. Expand Console Root\Component Services\Computers\My Computer\DCOM Config
3. Find "IIS WAMREG Admin Service" in the list, right click then choose Properties, and on the Security tab, click Customize.
4. Grant the Network Service account "Launch and Activation" permissions.
5. Click OK.

You may need to reboot.
