    Use the WSUS service (if not selected)

    I am assuming both require online access but they may be located on different servers and that's why I said:
    maybe changing that option might take one to a different server? Not sure though...
    Cheers friend!

    Microsoft has lots of servers.
    Both disms might or might not be on the same server{machine}.

    The /ONLINE means you are working with a active, booted system rather than a stored system image. I don't think it refers to the internet at all. Art least that's what I get from reading about it.

    Did you see the screenshots in post #3 ?

    They specifically refer to Windows Update & the WSUS server.

    Both on the internet.

    /Online

    Specifies that the action is to be taken on the operating system that is currently running.

    This option cannot be used with the /Image or the /WinDir option. When /Online is used the Windows directory for the online image is automatically detected.

    From Brinks tutorial:

    /RestoreHealth - (recommended) This switch option checks for component store corruption, records the corruption to the log file, and FIXES the image corruption using Windows Update. This should take around 10-15 minutes up to about an hour to finish depending on the level of corruption.

    Yup, agree with that, just not /Online parameter having anything to do with the internet. It defines what is being searched and repaired.

    The focus of this thread is related to one specific command that does access Windows Update. Moreover, it was never intended to address all the DISM variables that are available. Just one specific command string; period. And when David pointed to the online options that were available, you chimed in with "online doesn't always mean online" or something to that effect. Now, since you seem to be up on dism command strings, I will not dispute your claims, nor do I care to, because I only care about the one mentioned in my opening statement. And, I believe it is the same one you are trying to use right now to fix your own dism issue; correct? BTW, I think ectech is really providing you with excellent support to try and help you with your own dism issue and I wish you the best of luck in resolving it.

    Respectfully,

    Hello all,

    In summary, with two others forum members in agreement with my initial post and no forum members disputing the specifics of same, I am marking this thread as solved. Thanks to all who participated in this lively conversation.

    Best regards,

    Run sfc /scannow (first)
    This will attempt to fix any corruption from the resident component store
    (Note: internet access is not required)

    If the above is unsuccessful:

    Run Dism /Online /Cleanup-Image /RestoreHealth
    This will attempt to fix any corruption from an online Windows Update source
    (Note: internet access is required and may take a considerable amount of time on slow connections)

    Hopefully, if OK:

    Run sfc /scannow (again)
    This will verify that DISM was successful in repairing the errors

    Your thoughts on this issue would be greatly appreciated.

    In my case I found that the command ending in "/RestoreHealth" was not valid. It needed to be "/ScanHealth"
