Having a large number of workstations or servers within an enterprise brings a host of challenges in trying to maintain them.

A quick and easy fix is to go straight to the source. Dsquery is a command-line too that allows us to query Active Directory based on criteria we feed into it. Today we are going to focus on one common criteria used, dsquery computer, which finds computers in the directory that matches our search patterns.

I must admit I almost changed my DNS settings blindly and was glad I didn't after running a few benchmarks.
