While I was out at the Microsoft Certified Masters program for Directory Services a while back, I realized that I made a mistake in a post about NETLOGON SRV registration intervals.  Thanks to Microsoft Platforms PFE Matt Reynolds for helping me catch this error.  I apologize to everyone for the mistake in my post.  The traces which are attached to the original post show the correct intervals as you’d imagine but I didn’t do a good job of writing to that.  I have ...

!!! WARNING:  IT Systems Administrator blasphemy ahead !!!  Actually, here it is right here:  I know that NetDiag is a staple tool for systems administrators but I’ve never been a big consumer of the tool and that’s mostly because I just don’t care for it.  There is some great functionality in the tool but a lot of it can be found in other tools without all of the excess effort and output.  The other thing is that there are some limitations and known issues which often m...

As of 12:01 AM on Saturday, April 24th 2010, Tad Crandall and Richard Crandall are no longer Microsoft employees and will be focusing on cb5 full-time.  Though only gone for a short time, the news has generated several opportunities which we are working diligently to accommodate.   However, one of our goals is to take some time to refine our infrastructure and our web pages so over the next several weeks you may experience some minor downtime and changes.  Please bear with us...

A Nifty Trick to Backing-up AD Integrated DNS Zones Purpose                 A few years ago I had a customer that lost their DNS databases that were stored in AD. They asked me if there was any way to recover this data without performing an authoritative restore. That got me thinking of what we could use native to DNS that could provide backups and restores that would be affected by Active Directory as little as pos... [More]

Network Bandwidth vs. Network Latency Purpose                 It has always been curious to me that we accept a statement of bandwidth only from our ISPs, when latency is just as important. I may be able to send you an elephants weight (~8 tons) in gold over the next year, but wouldn't you rather have a mouse's weight every second until then (~700 tons)? Network latency is big deal. Too much network latency and we c... [More]

Network Ports and Sockets Purpose                 To begin to understand how a computer communicates on the modern network you need to understand network ports and sockets in TCP/IP. This is probably the most basic concept to networking. In Windows, and in other platforms, there are some tools that will also help us in reviewing our ports and connections on any given machine. I have no plan to rewrite was has alread... [More]

If we are able to export data from public folders we should be able to export data from mailboxes. What I have done is taken the same code used in the Public Folder to HTML blog but, just replaced the public folder commands with mailbox commands. Note: To be able to use the sortable feature you will need to download the JS script form this website, http://www.kryogenix.org/code/browser/sorttable/. I encourage changing the HTML output to reflect the needs of your environment. When you change th... [More]
