Why protect DNS?
[James Michael Stewart]
Active Directory depends upon DNS. If DNS fails, so does Active Directory. This, in turn, means that if DNS fails, your entire network may be disabled. So what will happen to AD if DNS fails? Find out in this tip.
Restricting cached credentials
[James Michael Stewart]
Windows operating systems, including 2000, XP, and 2003, cache the logon credentials for the last 10 users. This allows for the user to re-logon at a later date even if the domain controller cannot be accessed at the time of logon. While this does represent a fault tolerance to DC downtime and network congestion, it is a poor state of security. Find out what the most secure settings are in this tip.
Securing an administrator's computer
[James Michael Stewart]
In a modern Microsoft environment, the Active Directory database is arguably one of the essential assets of the network. Thus protecting AD is an important part of maintaining a productive environment. This tip discusses increasing security by locking down the desktop systems that administrators use to interact with AD.
Secure administration and administrator privileges
[James Michael Stewart]
You may have installation and setup procedures that ensure a secure domain controller, and you may have a tightly controlled physical access control system. Still, to keep your system truly safe, you need to have reliable people perform administration in a secure and controlled manner. This tip explains why.

ASK THE EXPERTS:
How can I restrict domain and workgroup names in AD?
Dear Laura Hunter,
I have a small network of 250 users who assign their own domain and workgroup names to their equipment. This is in violation of our local security practice so I have been trying to determine if I can restrict the domain and workgroup names allowed on the network. How can I do this?
