We have a small Work Folders implementation for a few clients.
Until recently, the function has been working great, no problems.
However, we have confirmed that two recent Windows10 patches leave Work Folders broken and completely unusable for clients who have either of the patches installed.
KB3185614 (security rollup for Win10 build 1511)
KB3189866 (security rollup for Win10 build 1607)
If a Win10 client has either of these updates applied, they cannot use Work Folders. The client attempts to connect to the Work Folders Server and gets the error:
"there was a problem finding your Work Folders server", error code 0x80072f76.
Work Folders server is fully patched.
Removing the patch will allow the client to connect and use Work Folders successfully, but as we know Windows10 will just reinstall that patch again in a few days. We are using the Microsoft "driver update" prevention tool for now to block the patch on affected machines.
We are opening a support case with Microsoft soon.
