Error When Trying to Install WSUS on Server 2008

Due to one of our server's operating system corrupting on us, we had to rebuild it with a fresh install of Windows Server 2008 R2. This server amongst other things ran Windows Server Update Services for our entire network.

We got everything reinstalled and working fine from scratch until it came to installing WSUS.

Everytime we tried to install the "Windows Server Update Services" role it would fail almost immediately with the following error.

"The update could not be found. Either the update is not applicable to this computer or the update no longer exists. Verify that the update still exists and is applicable to this computer from your WSUS server or Windows Update."

Change VMWare ESX/VSphere Host VLAN ID

Recently we had an issue where we had not set the VLAN ID on 10 new VMWare VSphere servers. This resulted in us being unable to manage the VMWare hosts, the only way to resolve this was to change the VLAN ID manually on each of the hosts.

If you find yourself in this situation, you can use the following procedure to change the VLAN ID in VSphere/ESX.

Log on to a VMWare VSphere or ESX host with your ROOT account.

At the prompt enter: esxcfg-vswitch -l

Setup Mobile Broadband on Dell XPS M1530

A couple of years ago I bought my Dell XPS M1530 Laptop. At that time I had the chance to include mobile broadband with the package. Unfortunately if I had I would have been tied to a 12/18 month contract etc. With the amount I was already paying for the unit, I decided against the extra cost.

This resulted in the laptop coming without a HSDPA module.

It was a good job I did, as I found out the other day that the modules that are factory installed are "locked." Fixed to the Vodafone network.

Time passed and a friend of mine introduced me to his new USB T-Mobile 3G dongle. 3.6 Mbits of highspeed, wireless broadband awesomeness. Then came along smartphones and the ability to use them connected to your PC for access to the internet, via 3G networks. All this is great and works very well, but having an extra piece of hardware dangling from your laptop can be annoying if your moving around. It was time for plan B.
