By default samba listens on two TCP ports- 445 and 139. You can
specify this in smb.conf
smb ports = 445 139
445 is the newer smb over tcp. 139 is the older smb over netbios
over tcp/ip. 445 was for Windows 2000 and newer clients.. I am
not sure why samba enables 445 by default since as far as I know it does
not support smb-over-tcp (without the NBT/netbios over tcp stuff.) If
you set "smb ports = 139" in your smb.conf you should see endpoint
I think what happens is Win 2000 (and newer) clients will initially try
to connect on port 445, find it isn't really compatible, and then "dump
down" to NBT on port 139.
So your NAS may be occasionally connecting on port 139 without problems
and occasionally connecting on port 445, and which point it fails.
OR- the "endpoint" errors may be completely unrelated, but you just
don't look for when when the NAS is working.
Is the NAS part of the domain? Is it a windows or linux/samba based device?
My samba server is a PDC. XP clients in the domain connect with no
problems regardless of if smb ports is 139 only or 139 + 445. XP/Win7
clients NOT in the domain can't connect to shares if 445 is disabled,
which indicates they are connecting to 445 1st.
