It was much earlier in the conversation. The SMB_COM_SESSION_SETUP_ANDX gave a MaxBufferSize of 4 bytes. This, obviously, does not cause any problems except for SMB_COM_TRANSACTION2 requests. Anyway, it's an easy way to crash NT 4.0. I don't know whether the bug has gone with service pack 3, however. Bye, Christian. -- Christian Starkjohann or , finger for PGP Public Key.
