In a typical installation with a fresh instance of Windows Sharepoint Services 3.0, one may regularly see a series of DCOM error events 10016 in the System Event log
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 DOMAIN\TFSservice SID {......}
The security permission can be modified using the Component Services administrative tool.
If one uses regedit to search CLSID {61738644-F196-11D0-9953-00C04FD919C1}, it refers to IIS WAMREG Admin Service.
This seems to happen both in Windows 2003 and 2008.
- Open Component Services from the Administrative Tools program group or special start menu folder.
- Drill down to Component Services > Computers > My Computer > DCOM config.
- Right click on hte IIS WAMREG admin Service node and select Properties.
- In the Security tab, click on Edit... in the Launch and Activation Permissions group.
- The Launch and Activation Permission dialog box should appear. Click Add... and type in TFSservice (which should be a domain user) and OK.
- For the new user entry, check Local Activation in the Allow column, and OK.
- OK the IIS WAMREG admin Service property dialog as well.
