Use o Credential Manager e especifique um nome de usuário de persistência "Enterprise" + senha
- Goto Control Panel -> All control Panel Items -> Credentials Manager
- Next to the heading "Windows Credentials" click on the link "Add a Windows credential".
- Enter the name of your NAS server ("NAS" in my case) and the appropriate credentials.
The result is an entry that has a persistence type of "Enterprise". This seems to do the trick. (I then restarted windows)
