Hi all,

when my Exchange Server 2003 SP2 starts it logs the following error into the

Source: DCOM
Category: None
Type: Error

The application-specific permission settings do not grant Local Launch
permission for the COM Server application with CLSID
to the user NT AUTHORITY\SYSTEM SID (S-1-5-18). This security permission
can be modified using the Component Services administrative tool.

For more information, see Help and Support Center at

Any ideas?

a similar one....

classID in the eventlog: {9DA0E10D-86CE-11D1-8699-00C04FB98036}
similar in dcom config: {9DA0E0EA-86CE-11D1-8699-00C04FB98036}

and this last one is MSEXCHANGEIS
