protocol to the server in packet number 11. The SNSLATC-NT NT4.0 server replies in

packet number 12 that Dialect #5 (the expanded SMB shows dialect #5 to be NTLM 0.12) is

accepted as the protocol.

After the client is authenticated, it maps a network drive on the CIFS/9000 Server that is a

member of the NT4.0 domain:

1. The client maps a drive: \\CIFS9000Severname\Sharename.

2. The CIFS/9000 server negotiates the authentication protocol with the client.

3. The CIFS/9000 server passes through the authentication request to the domain PDC

or BDCs, because it does not carry a SAM database to perform the authentication

locally.

4. The CIFS/9000 server negotiates the authentication protocol with the NT4.0 PDC or

BDC.

5. The NT4.0 PDC or BDC validates the client and replies to the CIFS/9000 Server.

6. The CIFS/9000 Server completes the mapping process and replies to the NT4.0 client

with a successful mount.

The following Network Monitor trace shows that the CIFS/9000 Server first negotiated the

NTLM v1 protocol with the client, then again with the NT4.0 PDC or BDC at the pass-

through authentication request:
