SharePoint 3 DCOM error - Event ID 10016

After a parallel SharePoint 3 install on SBS, DCOM errors began (event ID 10016):

"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). This security permission can be modified using the Component Services administrative tool."

While Google turned up several solutions, MS PSS determined what permissions where missing. Add them as follows:

1) Click Start -> Run, type "dcomcnfg" (without quotation marks) and then press ENTER.
2) Expand Console Root -> Component Services -> Computers -> My Computer -> DCOM Config.
3) Under "DCOM Config" locate IIS WAMREG admin service, right click it and select Properties.
4) Click the Security tab, under "Launch and Activation Permissions", click "Edit", add the NT AUTHORITY\NETWORK SERVICE and WSS_ADMIN_WPG accounts and add the following permissions:
Local Launch
Remote Launch
Local Activation
Remote Activation
