Being an administrator who handles no less than 1000 workstations and servers in a managed environment using Kaseya, one of the sickening thing to deal with is having to install/deploy the managed antivirus on machines with lots of conflicting applications. While Kaseya doesn't have the ability to silently remove any program applications **silently, it's necessary that you logged in remotely and manually remove/uninstall anything barring the deployment of the managed AV.

Thanks to Kaseya Live Connect. After several research and with the info I gathered, I am able to do the thing I need. One of the very powerful feature of Live Connect is the ability to perform execute commands via Command Shell like you're running it inside a Windows Box. So how did this help? Under Audit Page >> Add Remove >> Uninstall String, you will see uninstall strings you need to remove certain applications. See Figure 1 below:

Figure 1: Uninstall String

I have gathered some of the uninstall strings that I have proven to work flawlessly. I will provide my collection of working uninstall strings later on this post but let's just take for example the uninstall string for removing Microsoft Security Essentials. It is:

"C:\Program Files\Microsoft Security Client\Setup.exe" /x /s 

Take note: the quotes are necessary. Now, connect via Live Connect to your target machine and then click on Command Shell. See Figure 2 below.

Figure 2: Running the Uninstall String via Live Connect's Command Shell

Enter the uninstall string and then wait. Silent uninstall should take around 15 to 30 minutes. But having to monitor quite a number of machines, why should I bother waiting? But rest assured, when I get back with it, Microsoft Security Essential should then be cleared.

As promised, below are my tested uninstall strings with the working parameters. You may have to double check on the versions of the AV installed via Audit Page.
Microsoft Security Essentials:
"C:\Program Files\Microsoft Security Client\Setup.exe" /x /s 
"C:\Program Files\Microsoft Security Essentials\Setup.exe" /x /s 
Note: Check the exact path for the 64bit machines

The Samsung Galaxy Pocket is one of the upcoming smartphones from the Samsung range with a difference, with the title of this smartphone being a definite suggestion of its character. Samsung has been listening to the budget conscious amongst us, announcing a handset that, well, is exactly what it says on the tin; compact in size and very easy on the pocket!! This entry level handset is an ideal choice for those users looking for a lower priced unit that still offers an impressive performance and a quality brand. While sitting alongside the Galaxy S, S2 and upcoming S3, Samsung Galaxy Pocket contracts are much more affordable than those for the higher end devices.

The smallest smartphone in the Galaxy range measures in at only 103 mm x 57 mm wide whilst being 12 mm thick and weighing 97 g in weight.
Features include a 2.8″ touch screen, with a resolution of 320 x 240 pixels, utilising the TouchWiz UX user interface. The Samsung Galaxy Pocket runs on the slightly older gingerbread version of the android operating system and powered by an 832MHz processor. Although the unit only allows for an internal memory capacity of 3 GB, the integrated micro-SD card slot offers the possibility of increasing this to a much more respectable 32GB, for storing music or other external files.

The Samsung Galaxy Pocket comes with Wi-Fi connectivity as well as offering users the option to choose between 3G or EDGE for their internet connection. The unit also boasts Bluetooth 3.0, USB and GPS data connectivity. This ‘pocket sized’ smartphone features various pre-installed Google services such as; Gmail; YouTube; Google Maps; Search; Google Plus and more. Widgets can easily be installed or uninstalled as well as free and paid for apps available for download. Other features include; FM radio with RDS capability for the music lovers out there; a vibration and ring selection which allow the user to utilise MP3 ringtones as well as the conventional 3.5mm headset jack and loudspeaker.

Considering the small size of the smartphone, the battery used on the Galaxy Pocket is quite the opposite! It utilises a Lithium-ion 1200 mAh battery which should last for a minimum of 6 hours talk time. Finally this entry level smartphone offers a 2.0 megapixel snapshot style camera which performs at a screen resolution of 1600 x 1200 pixels. It also has the ability to record video at QVGA quality with about 15 frames per second and last but not least the unit comes with geo-tagging as well as sensors in the likes of Digital Compass and Accelerometer.

Unveiled at this year's Consumer Electronics Show in Las Vegas, the Xperia S marks the first attempt by Sony to produce a smartphone since it purchased Ericsson's 50% share of Sony Ericsson at the end of last year. The new Xperia phone still retains much of the design and branding of the smartphones that have been launched by Sony Ericsson in the past few years, but with complete control over the design and production many are expecting this to be a turning point for Sony in the smartphone industry.

Sony is a market leader in many areas of the electronics industry – including TVs and portable entertainment devices – but has never quite enjoyed the same level of success when it comes to phones. The split with Ericsson comes after a period of ten years when the partnership introduced many of the features we now take for granted on phones – including digital cameras and music/video playback.

One of the most disappointing things about Sony Ericsson phones over the past few years has been their inability to keep up with market trends and developments. At the start of last year the LG Optimus 2X introduced dual core processors, which have since appeared on the bestselling phones of 2011 including the Samsung Galaxy S2 and iPhone 4S. But Sony Ericsson's main offerings from last year, the Xperia Arc / Arc S and the Xperia Play didn't managed to incorporate this new development.

The new Xperia S (not to be confused with the Xperia Arc S) is the first dual core phone that Sony will release. At 1.5GHz and with 1GB RAM, it is one of the most powerful phones currently around. But is this too little too late? The industry is all gearing up to switch to quad core, and the first quad core phones could be unveiled either this week at CES or Mobile World Congress in February with quad core phone contracts being on sale within this quarter.

Perhaps this will put off some people who may be holding out for quad core, but the Xperia S still remains one of the most powerful phones running Android Gingerbread. It doesn't have Ice Cream Sandwich unfortunately, but on the plus side it appears that Sony has spent a lot of time revamping its Timescape system. Timescape was probably one of the biggest gripes that people have had with Sony Ericsson phones in the last couple of years as it was badly designed and caused severe performance issues. It looks like the new design not only looks a lot better but performs better too.

The phone also has a pretty decent camera – the 12 megapixel camera comes with LED flash and 1080p video, placing it slightly above the current industry norm. A 1.3 megapixel camera on the front is also one of the highest resolution video calling cameras on offer.

In terms of physical design, the Xperia S looks like it could be the biggest change for quite some time. The last several Xperia phones have all looked almost identical and this may have been one of the reasons why people started to lose interest. The new phone is fresh looking, and has a unique transparent band around the bottom that really sets it apart from a market full of very samey phones. The Xperia S is expected to be launched in the coming months, and like the Lumia 800 for Nokia, this could be a make or break device for Sony. So far things are looking good, and if Sony keeps it up they may be able to push themselves back into the market in a significant way.

Event ID	1059
Source	DhcpServer
Type	Error
Description	The DHCP service failed to see a directory server for authorization.

Try one of these solutions:
A. Restart DHCP Server service. Check you Event Viewer. Verify if you're getting Event 1044 on you System Log. This log confirmed that your server is now authorized to start and service clients.

B. On some other instances, restarting DHCP Server service doesn't work. Netsh should do the trick. Do this:
1. On your command prompt, run this command: "netsh dhcp add server ServerDNSServerIP"
Example: netsh dhcp add server dhcp.yourserver 192.168.0.101

This command adds the server to the list of authorized servers in Active Directory. Don't forget to restart the DHCP Server service and verify your System Log.
