Local branch site, not so well built (mostly non-managed switches).
By some weeks, suddenly, the network suffer some strange trouble: the
most suffering is samba (samba3 in NT mode, so SMB1): shares desappear,
if users try to logon when network is in trouble, they get errors like
'no domain controller available'.
Other traffic (eg, an internal HTTP) get slooooowww...
The network trouble happens randomly, and seems to hit only a piece of
the network, not all. Clearly, not always the same piece.
As came, go.
Looking at server and firewall, all seems OK.
Some hint on how to 'debug' this? Thanks.

Just in case you have missed it, SMB1 is disappearing fast, it is bound to totally disappear, so you should upgrade. In the meantime, can you post your smb.conf Rowland
