Hi everyone, I've used parallels and RAS for many years, but this is a brand new farm at a new company. I have all-new up to date 2016 servers. I just installed and activated the latest 16.5.1 build (20451). I'm trying to activate the user profile disk feature (have used it a lot in the past) on the first session host (2016). The host added fine with no errors. On my file server, I've created a UPD share (\\server01\upd). I have given the RAS server and the session host server full control permissions on the SHARE level and the NTFS level. Per this KB for 16.2, I even added the session host and RAS server as a local administrator (though that really shouldn't be necessary). No matter what, I consistently get the same error: [E 04/00000064/T175C/P0588] 10-10-18 15:32:04 - TS Agent RDSHSRV-01: [E 04/0000000F] Shared folder unavailable \\server01\upd\ I've tried just about every combination of setting out there, no luck. On my last 2016/15.5 farm, this was not an issue once I added the servers into the permissions.
