Nslookup–the Ultimate DNS Troubleshooting Tool

Ever need to troubleshoot DNS related issues?  Nslookup is the tool for you, and today I cover how to use this powerful little tool, along with some real-world examples.

This is part 3 of a 52 Web Pro Series for the web administrator.  Previous walkthroughs include:

Week 1 – Ping and Tracert
Week 2 – Understanding DNS zone records

All future videos can be found on the Web Pro Series landing page.

I’ll call this a “201 level” walkthrough although I haven’t decided yet how I’ll classify each week’s video.  This doesn’t require too much previous knowledge but it does move quickly and digs into DNS quite a bit—at least as much as can be done in about 10 minutes.
