Welcome to the site, my name is Jeff and I have been working in the IT field since the early 90's. Most of what I post here is related to work that I do for the various companies that I have worked for over the years. Please feel free to look around ask questions or post comments (if available).

  • Working with computer objects

    So I’m working with computer objects, if you can’t tell from my previous post. There are times when what you really want to know about a given computer is, who’s responsible for it. With good user education, your OU admins or computer admins will pre-stage a computer and populate the ManagedBy property. This effectively lets anyone who can read that property, know who is responsible for this object.

  • Active Directory Naming Strategy

    Does anyone have a good naming convention for Active Directory? It’s all completely subjective, what works for one organization is absolutely horrible for the next. Does anyone document what their naming convention is? Perhaps a better question would be, if you document it, do you follow it? How many people are aware of the 15 character limit on Window’s NetBIOS hostnames? How many know that limitation is still painfully applicable?

  • Does anybody really know what time it is?

    Or, How to fix your Novell clients so they don’t get hosed up times! If you don’t know this, when a computer in an Active Directory domain gets an invalid time it stops working. It has to do with Kerberos tickets and time stamps, and really it’s all very boring. Suffice it to say, that is the reason there is a w32time service. By default, Windows clients in a domain sync their clocks to the domain controllers.

  • The usefulness of TCPDUMP

    We are mid-firewall migration, it’s set to happen in about 2hrs from this post. But in the middle of trying to figure out why we are getting crazy network outages, we ran tcpdump on our dns/dhcp server. Why that server? That was the server that was identified by Central-IT as having issues.

  • One admin, multiple domains

    So I want to be able to have a single Django admin site for more than one domain. After talking it over with Carson, he showed me what needed to be done. It’s really quite simple when you talk to someone knowledgeable, and go over it from beginning to end.
