Alternatively, to enable unencrypted (plain text) passwords for the SMB client
on Windows NT 4.0 Service Pack 3 and newer systems, modify the registry in the
following way:

WARNING: Enabling this will allow unencrypted (plain text) passwords to be sent
across the network when authenticating to an SMB server that requests this
option. This can lessen the overall security of an environment and should only
be done after careful consideration of the consequences of plain text passwords
in your specific environment.

WARNING: Using the registry editor incorrectly can cause serious, system- wide
problems that may require you to reinstall Windows NT. Microsoft cannot
guarantee that any problems resulting from the use of the registry editor can be
 solved. Use this tool at your own risk.

Run Registry Editor (Regedt32.exe).
