Funny network behaviour

Georg Kreyerhoff

Hi,

In order to establish a security enhanced SQL server setup, I tried
to switch off network access by disabling all networking protocols,
so that the server can only be reached through a pipe. Nevertheless
the server was visible in the network and could be accessed from
all clients. Does anybody know what is going on here?

some more information on what I found out:

Even if tcp-ip and all other networking protocols are disabled in the
SQL-server configuration (only named pipes were enabled), Clients and Server
seem to be able to communicate via the Netbios-ports (Netbios-service
was still enabled on the machine). Do named pipes work over Netbios?
Or what is going on?
