The NET USE command returns "System error 240 has occurred. The session was cancelled" after 2 minutes, when trying to connect to a Native File Access for Windows CIFS server.
The NetWare CIFS server suddenly stops responding to incoming SMB_COM_NEGOTIATE requests. Normally, the NetWare CIFS server would respond with a selection of the latest CIFS Protocol Dialect "NT LM 0.12". A LAN trace would show that the NetWare TCP/IP stack acknowledges the income of the client's SMB_COM_NEGOTIATE request, but the NetWare CIFS server does not return a response. After waiting for a response from the NetWare CIFS server for about 2 minutes, the client will time out and return the error message "System error 240 has occurred. The session was cancelled" to the user.
Section "2.6.3 Connection Management" of the expired CIFS specification draft-leach-cifs-v1-spec-02 reads: "a server may terminate the transport connection when the client has no open resources on the server, however, we recommend that the termination be performed only after some time has passed or if resources are scarce on the server".
If you have configured the NetWare CIFS server to handle authentication in domain mode, then please ensure that you have specified both, the name and the IP address of the Primary Domain Controller.
If the Primary Domain Controller runs on a multi-homed Windows NT or Windows 2000 server, the NetWare CIFS server should be able to reach each IP address of the multi-homed server at UDP port 137 and TCP port 137 and 139, even though you can configure only one IP address with the CIFS configuration. This requirement is due to a defect with the NetWare CIFS server, which is reported to Novell engineering.
