support certain non-NT systems. Not recommended Following NT 4 Service

SMB servers such as Samba, HP LM/X, or LAN Manager for Unix unless plain text
passwords are enabled. To enable:

Hive: HKEY_LOCAL_MACHINE
Key: SYSTEM\CurrentControlSet\Services\RDR\Parameters
Name:
EnablePlainTextPassword
Type: REG_DWORD
Value: 1
