Hi Guys, I have couple of servers that are not taking any of the rollsups at all, every other update install correctly but the monthly ones fail, as far back as i can go its been like this, I have checked the updates through PS (Get-Hotfix) and went through them 1 by 1 lol and could not see any in there. Is there something i'm missing or should be doing as im at a loss. Cheers for taken the time to read this and if i'm posting in the wrong place pease let me know. Cheers

    If your installation media was a gold or RTM version then you'll need to install this set as a prerequisite. When 2012 R2 RTM'd the updates were called rollups and were not cumulative and they also had to be installed sequentially in correct order.

    https://www.microsoft.com/en-us/download/details.aspx?id=42334

    then at this point; or if you installed Windows Server 2012 R2 with Update then you can start using the cumulative updates here.
    the latest SSU

    followed by the latest Monthly Rollup
    The latest always contains new fixes plus the previous monthly update.

    Thanks for this really appreciate your time and guidance. I checked there and can see 2 of the updates are installed (KB4566425 and KB2919355) but not KB2919442. Would I better uninstalling these and then install them in the correct order or is it ok to install KB2919442 and tray the Monthly Rollup?

    Again thanks pal its good to know there is help out there :)
