6 comments on “Inaccessible Network Shares on Windows 10 1709

  1. Thank you for posting about this. I’ve run into a similar issue where shares were not being visible (ABE enabled). Did you ever figure out what exactly was going wrong here? In our case, newly created resources would work as intended pre-Creators Update but at some point later would stop working (disappear). Removing traversal privilege from the container after that point corrected the issue and I’ll be waiting a few days to see if it flip-flops back.

    For testing purposes we used the NTFSSecurity and the following PS function to set the permissions quickly. The skeleton folder simply consisted of a hierarchy of two levels (children & grandchildren containers and objects). File resource security groups follow AGUDLP group strategy.



    • I wish I had more info than I already posted, but unfortunately I don’t and have been too busy chasing other random Win 10 issues to investigate this further. I think basically MS broke traverse checking in 1709. I will say that once we made the change I posted about, we have not had any further problems.


      • No worries, thanks for the post; quite literally it was the only cogent post on this issue, and it seems sporadic. I was working on a folder yesterday where quite clearly something was going on, and to make the folder visible for the user I had to remove the traversal privilege, but when re-creating the ACLs from scratch with a new resource, traversal was necessary.

        I didn’t run into your problem exactly because our users already had parent directory privileges. I did notice the only users having issues had both Traversal & Generic Read checked, and removing traversal fixed it temporarily. Ultimately I ended up recreating the resource and the issue didn’t manifest after that (so far).


  2. Fall Creators update brought us some headaches. This post solved one of those problems that wore being very hard to find out the solution. Some of our shared folders are configured with based enumeration enabled and those woren’t acessible.
    Thank you for you post.

  3. i had similar issues. found it rather odd that once 1709 was installed network file access from my server changed. my mysterious issue is that my two Oppo Players can no longer access the network and these are the only devices that cannot see the network. i have other 1709 issues but not relevant to this topic.
