LM MD4 password check failed for user xxx

[rbrand at esg-gmbh.de]

Hello,

I have problems with samba-2.1 acting as PDC.

When I click on the samba machine in my NT-Explorer, I get
the message

"wrong passowrd or unknown username for \\share"

In the log-file I see the message

LM-MD4 password check failed for user xxx

What does it mean ?

Yours R. Brand
