Windows, by default, does not allow the use of a hosts file entry to alias a CIFS share to localhost. The typical error when attempting this would be “Incorrect username or password.” when navigating to the share.
To fix this, add a registry entry like the following:
- HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / Control / Lsa
- Create REG_DWORD with name DisableLoopbackCheck and value 1
No reboot is required.
