    As ever Jon very insightful, never knew about SID’s before this video of yours I’ll give this a go myself in my test lab
    Hoping to make another MS Teams video soon about teachers grading their student assignments and a student viewing their feedback
    Also did some work on in the test lab this week too by creating a bootable password reset pen drive using Rufus post Is on LinkedIn, have a look

    Great video. Are RIDs issued sequentially? If so, can I clarify that if you have multiple user accounts on a Windows computer with RIDs of 1115, 1116, 1119, 1120 that there are 2 user accounts which have been deleted (1117 & 1118)?

    • @ittaster

      Great question!! The answer is, sort of... It depends on how many domain controllers there are,. blocks of RIDs are handed out to DCs in the domain by the DC with the RID master role (there can only be one). Therefore where accounts are created on different DCs there would be a discrepancy.

    Hi John, what will happen if I forget to check generalized button on sysprep, then I capture the image and redeploy to several computers

    • @ittaster
      @ittaster  3 роки тому +1

      Hi Richard, /generalize is important as you point out. If the same image is deployed without 'sysprep'. The local SIDs on the computers would not be unique (local admin accounts, groups etc. ) It's not a good situation, especially in a peer to peer 'workgroup' environment.

      @@ittaster I know this comment is two years old, but isn't this a myth that was debunked awhile back. Do a search for Machine SID Duplication Myth. With that said, I still generalize.

      Hi, not built into the operating. I would tend to avoid changing with third party tools, they are unlikely to be supported and may cause issues.

      Hi, I think you may well be right! Microsoft documentation refers the uniqueness of SIDs for accounts, groups and computers, but is somewhat vague around DCs. However there is an article by Mark Russinovich that seems to suggest there is an exeception regarding DCs. Great question! Thanks for sharing👍
