SBS Server 2003 System State backup failing


I am using NT Backup on an SBS 2003 server and lately when it goes to take a system state backup it fails right away.  When I look in the backup log on why it failed, I see the following error code:

"COM+ REGDB Writer" has reported an error 0x800423f4

Any assistance would be a great help.

I found the following solution according to a tech support call to Microsoft:

First try the Soft Rebuild of the COM+ by following the below steps:
1.Go into control panel and reset the com configuration.

a. In control panel click "add remove programs".
b. Click "Add remove windows components".
c. Click the "Next" button (windows will re-initialize the COM

2. Look in "Component Services" MMC and make sure that the MS Shadow Copy Provider
does not show up as a COM+ application. The software provider should NOT show up
in Component Services on Windows 2003 and above. If it is, you will have trouble
initializing the VSS coordinator and provider instances.

a. In the Component Services MMC, navigate to "Component Services\My
Computer\COM+ Applications\"
b. View the properties of the "MS Software Shadow Copy Provider" if it exists.
In the "advanced" tab, uncheck the "Disable deletion" checkbox and then delete the
"MS Software Shadow Copy Provider" from COM+ Applications.

3. VSS biniries registartion:
net stop "System Event Notification"
net stop "COM+ Event System"
net stop "Microsoft Software Shadow Copy Provider "
net stop "Volume Shadow Copy"
cd /d %windir%\system32
net stop Vss
net stop swprv
regsvr32 /s ole32.dll
regsvr32 /s oleaut32.dll
regsvr32 /s Vss_ps.dll
vssvc /register
regsvr32 /s /i swprv.dll
regsvr32 /s /i eventcls.dll
regsvr32 /s es.dll
regsvr32 /s stdprov.dll
regsvr32 /s vssui.dll
regsvr32 /s msxml.dll
regsvr32 /s msxml3.dll
regsvr32 /s msxml4.dll
net start "COM+ Event System"

4. Disable VSS tracing if it is enabled.

5. Reboot the system to bring all writers into a stable state.

After that perform the System State Backup of the server.

I hope this helps,
