> Are you saying that the second "process" is a different UNIX process?  My tests show otherwise.  From what I can gather, this is all happening over the same TCP connection to the same smbd process.  I am specificly talking about multiple requests, not multiple network connections.  smbstatus, netstat and ps show that multiple SMB connections to different shares use the same TCP connection and smbd process.

jeremy's probably right.  have you seen his message?
