Dynamic Phone Directory Implementation

25 June 2018

Let me guess. Printed out and on your desk in the smallest font visible to man's naked eye is an excel spreadsheet with all the phone numbers of your unit listed. It's likely right next to a $500 Cisco Voice-over IP computer phone. To dial a number, you'll break out the bifocals and painstakingly use your finger to line up to the right number on the spreadsheet and punch it in manually on the phone fatfingering the dial pad 10% of the time. Sound familiar?

Wouldn't it be nice if that $500 computer phone could geterate an easily navigatable directory that was as up to date as the listings in the Call Manager? Well, thats exactly what we had in mind when developing the Dynamic Phone Directory (DPD)

Hyper-V Domain Controller Time Problem

23 October 2015

With computers, usually the simplest answers are the hardest to find. For example, for the past several months, my home's domain time has been off by a couple hours. The task of fixing it was put on the back burner because I didn't know the simple answer to it and when I finally got around to trying, I simply couldn't find the answer. 

As with most things in a computer, it came down to a stupid checkbox being checked. 

Problem: A Hyper-V Domain Controller had the wrong time and kept resyncing to the wrong time

ESX install onto M65 Problem

21 January 2013

This is probably not a problem that is going to effect much more than .00001% of anyone in the IT community, but it did affect me and successfully killed about 30 hours of my life in troubleshooting. Lucky me. These are just some quick technotes mainly consisting of workarounds rather than real solutions.

Task: Install ESX 3.5 on a Dell M65, 32 bit laptop.

Problem 1: ESX Image will not install initially due to the following error:

Installation Operation Failed!
Unable to find a supported device to write the VMWare ESX Server 3i 3.5.0 image to.
(The rest ommited)

Domain Census Script

12 November 2012

An example input and output file is attached.
