Opening COMEXP.MSC or DCOMCNFG.EXE and navigating to Component Services\Computers\My Computer will result in the following on-screen error:
Event ID: 4434
Task Category: Security
A method call to an object in a COM+ application was rejected because the caller is not properly authorized to make this call. The COM+ application is configured to use Application and Compoinent level access checks, and enforcement of these checks is currently enabled. The remainder of this message provides information about the component method that the caller attempted to invoke and the identity of the caller.SVC/Lvl/Imp = 10/6/3, Identity=<<DOMAIN\Username>>
This issue is fixed in USMT 5.0. The recommended solution is to use USMT 5.0 for migrations instead of USMT 4.0. USMT 5.0 is part of the Windows Assessment and Deployment Kit (ADK):
To workaround the issue in USMT 4.0, you must specify a config.xml file and set the “Microsoft-Windows-COM-ComPlus-Setup” to not migrate.
If you are not already using a config.xml file for USMT, you can generate one automatically by specifying the /genconfig switch to scanstate.exe syntax. For example:
scanstate.exe /genconfig:config.xml /i:migdocs.xml /i:migapp.xml
For more information about USMT and config.xml files, see the following Microsoft TechNet Article:
Once you have generated the config.xml file, you must edit the following section, depending on source operating system (OS):
From an administrative command prompt, run these three commands:
Verify that R000000000001.clb is present. Then, copy it from the current directory to the root of the C drive by running this command:
Next, copy and paste the following VB script (between the dashed lines) to a.txt file and rename it COM_Restore.vbs (make sure to change the .txt file extension to .vbs).
Set objComCatalog = CreateObject("COMAdmin.COMAdminCatalog")
MsgBox "Backup Restored!"
Set objComCatalog = Nothing
Save the script to the root of C:\.
From the command prompt, run this command:
Finally, open Component Servers (dcomcnfg.exe) and see if you are still getting errors.
Note If you are logging in as a non-admin user and trying to start Component Services, the Event ID 4434 is expected. Non-admin users are not part of the administrator role of the COM+ System Application and, therefore, the security warning will get logged in the event log. This does not mean that the COM+ catalog is corrupted.
