I have setup WSUS 301. Most target clients have been reporting. However, I have noted on reports that some computers were not updating. What appears to be common among those failing to update is BITS. While it is set on Automatic, this service is not starting. WHen manually run, it comes up with service-specific error code - 2147467243. I have ran the command 'wuauclt /detectnow" to no avail. I have also deleted the Downloader folder in the alluser profile (C:\Documents and Settings\All Users\Application Data\Microsoft\Network\Downloader) and other than it gets recreated after running the 'detectnow' command, BITS still fails to start.
Would appreciate help to solve this issue.
