Customized onsite training, network troubleshooting, installation and design since 1999 ...because one size doesn't fit all.

MS Networking and TCP/IP - Full Day

 

This course will review Microsoft operation, implementation, design and support.  The instructor will be able to determine which technical areas to focus on and the students get a opportunity to review network concepts from a tactical perspective.  Network basics are reinforced with hands-on examples in a collaborative environment.

The “So What?” lesson is reviewed with the students after any important concept is presented.  This will ensure the instructor and students fully understand the theory or concept just presented.  The goal of the course is to empower the students with enough knowledge that they can immediately use.  The habit of questioning leaves them with an inclination to understand new technology and become an efficient troubleshooter.
