| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 0 |
Determines whether the SMB redirector can send unencrypted passwords to servers that request them.
The SMB redirector always sends encrypted passwords unless a server specifically requests an unencrypted password. If the value of this entry is 0, the SMB redirector sends only encrypted passwords. If a server requests an unencrypted password, the request fails. However, you can set the value of this entry to 1 to force the redirector to send an unencrypted password when a server requests one. This permits you to connect to SMB servers that do not support password encryption, such as Samba, Hewlett-Packard (HP) LM/X, or LAN Manager for UNIX. Microsoft SMB servers never request unencrypted passwords.
| Value | Meaning |
|---|---|
| 0 | The SMB redirector sends encrypted passwords only. Requests for unencrypted passwords fail. |
| 1 | The SMB redirector can send unencrypted passwords to servers that request them. |
