O mito da duplicação de SIDs
So is having multiple computers with the same machine SID a problem?
The only way it would be is if Windows ever references the machine SIDs
of other computers. For example, if when you connected to a remote
system, the local machine SID was transmitted to the remote one and
used in permissions checks, duplicate SIDs would pose a security
problem because the remote system wouldn’t be able to distinguish the
SID of the inbound remote account from a local account with the same
SID (where the SIDs of both accounts have the same machine SID as their
base and the same RID). However as we reviewed, Windows doesn’t allow
you to authenticate to another computer using an account known only to
the local computer. Instead, you have to specify credentials for either
an account local to the remote system or to a Domain account for a
Domain the remote computer trusts. The remote computer retrieves the
SIDs for a local account from its own Security Accounts Database (SAM)
and for a Domain account from the Active Directory database on a Domain
Controller (DC). The remote computer never references the machine SID
of the connecting computer.In other words, it’s not the SID
that ultimately gates access to a computer, but an account’s user name
and password: simply knowing the SID of an account on a remote system
doesn’t allow you access to the computer or any resources on it. As
further evidence that a SID isn’t sufficient, remember that built-in
accounts like the Local System account have the same SID on every
computer, something that would be a major security hole if it was.
