Want to learn more about DNS? Then pick up this free book from Infoblox while their supplies last. 

DNS on Windows Server 2003 was authored by Matt Larson, Cricket Liu, and Robbie Allen and covers just about everything you need to know to manage DNS on a Windows 2003 server. Granted, most organizations have already retired their 2003 servers for 2008 or another platform, but the content is still fairly relevant and there are chapters that are focused on the technology rather than the operating system specific implementation tasks.

So, what do you have to do to get the book?

If you are thinking about studying for the CCNP and aren't sure how big of a bite you are about to take, or if you have already started and are looking for some additional study resources, then keep reading. Cisco Press released their 642-902 CCNP ROUTE Official Certification Guide in early 2010 in anticipation of the CCNP exam refresh. Here's what it looks like:

If you want to check out a couple of the key chapters (EIGRP and OSPF), then here they are in a free digital format:

I guess the big news of this is that it's FREE...as it should be :). Cisco has started to develop some quick training describing how to enable features on the ASA/PIX firewall. Some of the topics are neat..."How to set up Packet Tracers" "How to set up SSL VPNs." The modules DO actually describe how to do these things if you can bear the pain of listening to a computer generated voice reading a script someone wrote. Sure isn't as good as the Cisco training available from Jeremy Cioara on CBTNuggets (ehem...shameless plug). It sounds like the voice that announces the names in my airport...Anyhow, the link to this training is here!
