I remeber in my training something about the Schema master should be created then disconnected from the network and kept off-line can anyone explain this please? Is it for security? What is the official line?
 
Rich,

This is not accurate. The Schema Master is one of the five FSMO Roles (
Schema Master, Domain Naming Master; PDC Emulator, RID Master and
Infrastructure Master ). The first two are Enterprise-wide roles and the
last three are domain-wide roles.

Only a Domain Controller can hold these FSMO Roles ( by default the first DC
in the domain / tree / forest holds all five ). You do not want to take a
DC off-line for an extended period of time ( tombstone life = 60 days, by
default ) otherwise you start having lots of fun errors.

HTH,

Cary

Person that can extend schema must be part of Schema Admins group, so it is
enough for schema master to be safe, not to put anyone in Schema Admins
group. I haven't heard of recommendations of keeping schema master offline.
Organizations normally use empty root domain to protect Schema Admins and
Enterprise Admins.

But Schema itself would still be vunerable to hack right,
which for an enterprise could be serious.
 
Schema does not reside on Schema master, but it is available on any DC, but
it can only be changed on schema master server, but if anyone hacks your DC,
he can seize schema master on DC and thus modify schema. Putting schema
mater offline doesn't improve your schema security.

I wonder if Rich is confusing the Schema Master and Certificate
Server. The recommendation is that the root Certificate Server (if you
have one) is best kept offline unless it is needed to serve a
certificate, in which case it can be brought on line.
