I would recommend blocking those ports (135, 137, 139 and 445) at the
edge router so that at least they aren't sent over the internet. For
some machines, perhaps you want a host firewall to block them from
leaving the box at all.

Subject: Avoid sending current credentials automatically over the
network
Hi all
When mapping a network share without any credentials parameter or when
clicking in a link for a internal app Windows and IE automatically send
the
current users credentials automatically. Aparently for IE you can
configure
to send anonymous creds (guest account) and then ask for creds.
However over the network there is no option to avoid sending current
users
creds automatically. I tried smb signing but it didn't work.
Does anyone know a solution for it?
Thanks
Uno
