So what do. The very simple thing is to try to remember what you could have set your password. Most people use their name and birthplace along with an important number (Such as their birth day, month, or year). Some people will use pet names with or without numbers. Before we reset the password think for some time what it might be. Even try sleeping on it. You might remember what your password is the next day.

Contractors definitely represent a unique security challenge. Unlike typical guests, who are there for just a short time and need only Internet access, contractors - especially long-term contractors - are much closer to employee status.

Avoid the Pains from Active Directory PDF Print E-mail
Written by David Noel-Davies   

Over the past eight years I’ve helped plan, implement, and operate various Active Directory (AD) infrastructures. And as much as I value AD’s power and strength, I’ve also learned quite a few annoying things about AD that sometimes prevent it from operating as smoothly as possible. In this article I discuss some of these annoyances and explain how to best work around them.

Special Hardware Problems
In general, all AD domains are rather tolerant to hardware problems that take down a single domain controller (DC). Of course this is only true if you follow the best practice of implementing more than one DC per domain and if you continuously monitor that they’re replicating the changes amongst themselves. This way, if one DC fails for some reason, clients wanting to authenticate to the domain will leverage DNS to find another DC in the network to connect and authenticate to. For normal operations, no problems occur even if one of the special Flexible Single-Master Operation role-holder DCs goes down for a few hours or even a few days. AD is designed to operate without all the FSMO DCs being available all the time. Obviously, you shouldn’t update your schema or mass-create new objects in your domain when specific FMSO DCs are down. But normal operations, such as users changing their passwords or administrators adding an occasional new object to the domain, will still run. This is one of the key strengths of AD and its multi-master replication model.

DNS Active Directory Rescue Planning PDF Print E-mail
Written by David Noel-Davies   

A few years ago (and them some!), I received my scuba certification. The most valuable lesson in that class: Stop, think, and do a little planning before you jump into the water. Failure to heed this warning could cause the bends, or possibly death. Our instructor's mantra: Plan your dive; dive your plan.

The same philosophy applies to network administrators performing large upgrades or implementing a new technology that could affect production. Too often I've seen otherwise competent technologists paint themselves into a corner because they lack a clearly defined implementation roadmap. Instead, they simply pop in the upgrade CD-ROM, double-click setup.exe, and walk through the wizard. This approach almost always leads to disaster.

Extending Active Directory Across Platforms PDF Print E-mail
Written by David Noel-Davies   
 Some machines just don’t die. You know this, especially if you deal with any UNIX or Linux systems. And maybe you know some UNIX guys and gals whose motto was “mess with my UNIX system over my dead body.” Those guys are still around, too. But compliance requirements are altering their jobs and yours, especially if your IT department manages across platforms.

Now the word from above is “extend Active Directory to UNIX and Linux systems” or maybe the word from above is just “Do it.” Symark Software believes it can help. Its PowerADvantage product offers a unified log-in solution that brings Active Directory (AD) centralized authentication, policy enforcement, and infrastructure management to UNIX and Linux systems.
