ACL Settings in Thecus NAS Prevent Connections

Yesterday I set up protections on shared folders in my Thecus N5550 NAS using the ACL settings (you can set permissions for specific users created in your NAS GUI).  Today I tried to access these folders on my NAS, and Windows 7 wouldn’t let me!  There was no option to enter the login credentials I created for the folders yesterday, and no way to make the NAS recognize my Windows credentials.

I searched for a while and found this (mysterious and not very solid) answer on the Thecus Forums:

1. Opened Network and Sharing Center
2. Opened Change Advanced Sharing....
3. Changed the last setting to "Use user accounts and passwords..."
4. Closed that and changed my active network type from "home" to "work"

Not sure exactly why it worked, but it did. Now I can enter my username (no need to add after the username) and pw to browse my ACL protected folder.

Thanks to user jonathan.morris for posting!  I too am not sure why this works, as I have not set up the ACL on the folders with my Windows credentials, nor did I enter the NAS user credentials I set up yesterday, but suddenly there is no issue accessing the NAS Share Folders directly via Explorer (which has me wondering how effective the ACL setting could be since I’m accessing the folders without entering any user/pass).

Windows advises that you should let it monitor and control your home network, but if I can’t USE my home network to access my NAS, Windows certainly isn’t doing its job correctly.
