Windows Explorer – Cannot Read From the Source File or Disk

Sometimes when users on a Mac manipulate files on a Windows network share, files get left with missing attributes where there is no security tab in the properties, you cannot take ownership of the files nor can you delete them and you get an error message that states “Cannot delete file: Cannot read from the source file or disk.”.

Asterisk Dialplan Module – stdexten

Very similar to the stock version of standard extension in extensions.conf on Asterisk 11 with some minor customizations to the variables passed to it. Technically, this is not what I’m calling a “module” (which is actually a subroutine), this is just an example of the stdexten context which some may find useful.

In my scenario, under no circumstances would there be any reason to have to change the voicemail context, so the arguments that get passed are: The devices to ring, the timeout period (how long to ring the extension), and the destination voicemail box. If neither of the second and third arguments are passed, then it assumes a timeout period of 25 milliseconds and the extension passed in argument one as the voicemail box.

Asterisk – Modular Dialplan

This is just a table of contents of the various Asterisk dialplan modules I have created over the last couple of years and am releasing to the general public as open-source in hopes that somebody finds them as useful as I do.

In my days as a Network Administrator managing six interconnected, fully-meshed branch office PBX’s at a telemarketing firm, maintaining six separate dialplans became a tiresome effort which ultimately led to my creation of the dialplan modules.

Exchange 2010 OWA – Outgoing Attachments Not Visible in Compose New Message Window

For about the last nine months to a year, I have been having ongoing problems with Exchange 2010 OWA with SP3 not showing attachments on outgoing emails. Even though the attachments would still get delivered, the location where the attachments would normally show up had completely disappeared and you couldn’t remove items after attaching them. I can personally vouch that this issue affected IE8, IE10, IE11 on PC and Google Chrome on MAC. As for Firefox or Safari, I can’t really remember whether they were affected or not and since it’s already fixed I have no way of testing it.

Windows Update Error 8024402C – Bypass WSUS for VPN Computers Joined to the Domain

For remote teleworkers who have computers joined to a domain running Windows Server Update Services (WSUS), to overcome Windows Update error 8024402C, via the registry, you will need to force the computer to bypass your WSUS server by setting the “UseWUServer” DWORD value from “1” to “0” and then restart the computer.

Ubuntu Server – Apache 2.4 Upgrade Changes

As many of you may have noticed, upgrading to Apache 2.4 can either cause the “apache2” service to fail to start altogether or may render your websites more or less inoperable. Luckily, there are only a few minor changes to look for that will hopefully get you back up and running with a minimal period of downtime.

  1. During the upgrade, if you decided to keep your original versions of your config files like I did (always a good idea), you will then end up with some extra files with “.dpkg-dist” on the end of the filename. These are the latest version of the config files. As a best practice with any major config file changes, I would suggest to create a backup directory and get in the habit of copying any files with the date in the filename before you make changes. There have been many instances where this has come back to bite me in the past and I have learned my lesson over the years so save yourself some time, stress, and headaches. 
    cd /etc/apache2
mkdir backups
mv apache2.conf backups/apache2.conf.09_25_2014

Carrier Access Adit 600 – Reset to Factory Defaults

Carrier Access Adit 600
Carrier Access Adit 600

Today I ran into a password issue on a refurbished piece of telco equipment that I got for a great price at refurbphoneexchange.com, the Carrier Access Adit 600.

Just a little background info, these units are great for converting a couple of T1s from a Sangoma or Digium card in an Asterisk server for up to 48 FXS ports and are very solid performance wise. When compared to a Rhino box or other similar device that provide the same functionality, it’s like 1/5th of the cost. As far as I know, the only downside is that they are out of production and there is a limited number of units out there. Also, I haven’t been able to find any firmware updates anywhere for these units on the interweb. The company has been bought and sold so many times it is hard to keep track of who to call for support. It was Dell Force 10 Networks but now the current company that owns rights to the product is Telmar but I’m still having trouble finding answers to my questions.

Windows 8/Server 2012 – Install A Theme for All Users

On Windows 7, 8, and Server 2012, themes can be downloaded from Microsoft here and are typically installed on a per user basis in the following directory:

%localappdata%\Microsoft\Windows\Themes

To install a .themepack file for all users, it requires a bit of manual intervention. Today when searching for the answer, I found this perfect blog article that explains exactly how to do it so there’s no real point in re-writing it all verbatim here.
