Hi. We have recently seen a number of individuals running W10 build 1709 and WSA 188.8.131.52. File shares have become unusable, resulting in a "folder path not found" error in other W10 clients and even from the host PC itself. In all cases, we have found that the host PC can see its own shares, but gets that error when opening them. Other clients get that message when trying to connect to the host, before listing the shares. All of the affected were being managed by the workstation policy with Identity Shield enabled.
We have found that after uninstalling the WR client from the portal, and restarting the host PC, that all sharing/access issues are resolved. As yet, we have not reinstalled WRSA on any of the affected machines and all of the affected are being managed by an alternative AV until we can identify what is causing this.
