Hi,
As far as I know, there are three possible causes for this specific
problem (NTBackup fails with 80042301):
1) The COM+ Event System service was manually disabled (open
services.msc and, if this is the case, re-enable this service). This
service should be enabled by default.
2) There was a problem in the final phase during Windows Setup. To
double-check, just run the following command:
REG QUERY HKLM\System\Setup
If the SystemSetupInProgress or UpgradeInProgress values are different
than zero, then something wrong happened during setup, and you will
get the 80042301 message.
To fix this issue in this case, please run the two commands below:
REG ADD HKLM\system\setup /v SystemSetupInProgress /t REG_DWORD /d 0
REG ADD HKLM\system\setup /v UpgradeInProgress /t REG_DWORD /d 0
3) The COM+ infrastructure failed to properly install during Windows
Setup. To reinstall COM+, please follow the steps from this KB
article:

Please let me know if the problem could not be fixed with the steps
above.
In addition, can you look if there are any VSS and COM+ errors in the
Event Log? If yes, can you copy & paste them in your reply? Please use
eventvwr to copy & paste the events since the private data might also
be useful.
Thanks, Adi
