DCOM Access denied on Server 2003

Posted on 2011-05-04
Last Modified: 2012-05-11
I'm working on installing a new backup solution in my network.  The system uses a client/agent model.  I have a 2003 server, that's an active directly/domain controller.

When I try to connect to this unit via the backup appliance it fails with access denied.  So I went ahead and downloaded the MS DCOM client\server test application ( and ran.  On running I get a return of 'access denied'.  I'm logged in as the administrator.    

Any Thoughts?

    open Component Services console, expand to "My Computer", select the "COM Security" tab and edit both Acces and Launch and Activation permissions.

    I added both administrator and administrators to both, and gave allow to all items - still getting the same issue.  I'm logged into the client side PC as the DOmain Administrator account

    add the "Everyone" to the "Access" and "Launch and Activation" ... even if it is just for debuging.

    OK - making progress.  Under Component Services->My Computer-> Default Properties -> "Enable Distributed COM on this computer" was unchecked.  I checked  it, but am snow getting a different error in the DCOM test utility:

    C:\test>tstclnt thresher
    Client: Creating Instance...0.0229 seconds
    Client: CoCreateInstanceEx: The server process could not be started because the
    configured identity is incorrect. Check the username and password.
