I think we may be talking past each other. I was referring to (client) machine trust accounts inside of AD, not hostnames in DNS. I now think you are referring to the latter. I can see how that can work. -- Grant. . . . unix || die smime.p7s Description: S/MIME cryptographic signature __

IANAL, but even if one considers this scenario to constitute a DDoS attack, and there is plenty of case law supporting prosecution under CFAA (Computer Fraud and Abuse Act) for DDoS attacks, CFAA generally requires *intent*, and this appears to be simple negligence. "Trespass to chattel" might

Domain Controllers certainly need to have their hostnames registered in the AD domain, but regular domain-joined members do *not*. We've been running AD for decades, without registering members in the AD domain. Works fine. Instead, we get our (non-Microsoft) DHCP servers to register dynamic cli

We do something somewhat similar with our LAN. We have a new cable connection and an old DSL connection. The cable is 60x faster, but has a dynamic IP and blocks various ports (esp. 25), so we keep the DSL so we can send email directly etc. Obviously, we don't want to stream video or even do much

Traffic shaping is not my area of expertise, but from what I understand, at a minimum it can classify different kinds of traffic, based on more reliable metrics than DNS name. I was assuming (perhaps incorrectly), that its output (QoS markings or CoS or whatever) could then be used in a degenera

There is no way to know if this is the "right" or "wrong" approach without actually trying it and see what happens. Guessing the potential background domains used by Microsoft / Steam, etc and monitoring bandwidth used by those domains is unfortunately the only option available. It's not like any

Hmmm... My understanding was that the only requirement was that the DNS server pointed to by the AD DC (in this case the AD is managed by SAMBA) had to be authoritative for the domain in DNS which represented the matching AD domain. This was a common holy war between MCSE folks and Bind groupies.

@all I still do not see any relevant point that will take the DNS authority leaving the AD and do something to resolve your queries. As the wiki says, security is essential and you do not have to risk it and let the data be compromised. And remember, I'm at an education institute with courses in
