I just got a string of these events today. Never recieved them before. I don't run windows automatic update either. The error is below. I checked the file that it tried to delete and found that its creation date was after the event occured so the file must have finally deleted and allowed it to be recreated. The event repeated 30 times in 2 seconds. Does anyone know the cause / solution for this? Event Type: Error Event Source: ESENT Event Category: General Event ID: 485 Date: 4/20/2010 Time: 10:02:55 AM User: N/A Computer: servername Description: wuaueng.dll (880) SUS20ClientDataStore: An attempt to delete the file "C:\WINDOWS\SoftwareDistribution\DataStore\Logs\tmp.edb" failed with system error 5 (0x00000005): "Access is denied. ". The delete file operation will fail with error -1032 (0xfffffbf8). For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Hi , register the below files using regsvr32 regsvr32 %systemroot%\system32\wuapi.dll regsvr32 %systemroot%\system32\wuaueng.dll regsvr32 %systemroot%\system32\wuaueng1.dll regsvr32 %systemroot%\system32\wucltui.dll regsvr32 %systemroot%\system32\wups.dll regsvr32 %systemroot%\system32\wups2.dll regsvr32 %systemroot%\system32\wuweb.dll regsvr32 %systemroot%\system32\softpub.dll and let us know if it resolved the problem

I haven't performed the above steps because the events haven't repeated themselves since I excluded the file location from my virus scanner. If they repeat I will try to register the drivers again. Thanks.

Had a similar error, Event ID 485: Catalog Database (956) Catalog Database: An attempt to delete the file "C:\Windows\system32\CatRoot2\edbtmp.log" failed with system error 5 (0x00000005): "Access is denied. ". The delete file operation will fail with error -1032 (0xfffffbf8). Performed the DLL registrations above. These failed: regsvr32 %systemroot%\system32\wuaueng.dll regsvr32 %systemroot%\system32\wuaueng1.dl regsvr32 %systemroot%\system32\wuweb.dll regsvr32 %systemroot%\system32\wucltui.dll I found a post that said if you disable UAC for your account, wuaueng.dll would succeed, and this worked after disabling UAC and rebooting. The other 3 still did not load, but I have no more Event Log errors and the SMS client installed correctly with one exception - an error stating it "failed to schedule Software Protection service for re-start" (Event ID 16385). I restarted the Software Protection service and no error, so knock on wood....
