|I am running Vista Ultimate and on 02/05/08 windows update stopped
| functioning. Any attempt results in the 8024402F error message.
| I've spent five straight days on google, microsoft, and every other source
| and seem to be moving backwards on the problem rapidly.
| Some of the items I've tried:
| 1) Various stop/start solutions around BITS and Update service, including
| blowing away all of its history.
| 2) Eliminated all routers, firewalls, etc. from my environment.
| 3) Added/removed/readded trusted relationships with all of the various
| microsoft sites.
| 4) Attempted update through proxy server.
| 5) Performed a system recovery (not reinstall, just repair)
| 6) Attempted to set system back to date prior to failure.
| I can also see the detailed messages in the windowsupdate.log and the
| specific line where things start going wrong is:
| 2008-02-27 21:28:51:080 1032 ff0 PT WARNING: ECP: Failed to validate cab
| file digest downloaded from
with error 0x8009001d
| (I've done extensive search on the 8009001d message and it leads to the same
| places as the 8024402F)
| Having just finished six months of getting the system back up to spec with
| all of my software, the last thing I want is to start over again. Although I
| have extensive backups, the problem seems to be fundamental to the operating
| system as restoring backups does not work.
| I have discovered an interesting new twist which I have also come up
| completely empty on.
| Due to the extensive work over the last several days, I uncovered an obscure
| error with the file: c:\windows\system32\dssenh.dll, where windows is
| reporting that the hash of the file is incorrect and the file is corrupted.
| I can absolutely confirm, within the abilities I have to test, that the file
| is in fact perfectly fine. A hash using 3rd party tools against another
| Vista install shows the file to be identical.
| I also ran the SFC tool to scan and repair the file, but it reported no
| problems. I am only seeing the error in the Event Viewer.
| I'm running out of options and any input would be appreciated.
