You can’t update the updated driver

I regularly update my laptop. In addition to the Windows update site, I like to periodically check either the manufacturer’s site of the laptop or the component manufacturer’s site. I like to optimize my computer at the most. I have to unleash the full potential of each piece of hardware. Virtualization is a tough job.

On the manufacturer’s site, I can find drivers for chipset, video adapter, RAID controller, etc. These drivers are the latest versions published by vendor. Often they are newer than drivers in the Windows archives. Continue reading

Windows update error 80244022

A few days ago I updated my office laptop to Windows 10 build 1703. This part passed fine. However, after the reboot, Windows update reported an error with code 80244022. The explanation of this error is unclear – something went wrong.

After a few restarts, many retries, even deletion of the Software Distribution folder from the Windows folder, I searched the Net. Many answers were like “it’s just gone”. As my error isn’t just gone with the wind, I knew that it’s time for the HEV suite, crowbar and deep dive into the world of logs and Windows services.

“Greasy cloth” in the Internet link

A few weeks ago, I had a small project to replace one ancient Cisco router with one new MikroTik RB 2011 device. To make a long story short, I investigated the old Cisco configuration and then configured MikroTik.

After a few hours, I had the phone call. The local admin called to tell me that their Internet was terrible. There shouldn’t be any problem at all, as they are using the fiber optic link. Therefore, I connected remotely to the MikroTik device and checked its configuration.

How to find the Windows system uptime using the command line

Occasionally, when I’m working on a server, I need to check its uptime. I can find this information using several different ways, but often I’m in the middle of the command line session and I don’t want to leave my keyboard and search for the mouse.

At such times, using the command line is the best way to achive the goal. I will show you the two handy ways in which you can do this.

Removing BUSY leases from MikroTik DHCP pool

Whenever we’re designing a network, we’re trying to assign at least one continuous block of IP addresses for an automatic client assignment. Using the DHCP server, we can make network administration much easier. We can even use the DHCP server to assign an IP address for the servers in our network.

When the DHCP server spots a previously existing IP address from its DHCP leases pool, it will block that address from further assignment. This mechanism will prevent duplicated IP addresses in the same network segment.

Redirecting your USB drive to the VirtualBox VM

Although VMs are not real machines, they are computers, too. Today, in everyday work, we need to exchange some information between computers. Often, we will need to copy some information, maybe configuration data or files between our host computer and VMs.

While we can copy information and even files using the features Shared clipboard and Drag and drop, we don’t always want to duplicate data. This is even more important if you’re using an SSD drive in your computer.

Changing SID of cloned VMs

The fastest way to build a larger virtual environment (either test or production), is to install one VM and then clone it. This process is not the same for every environment. Additionally, it depends on the mechanism of the VM cloning process.

Additionally, every computer in the AD domain has its own identification. This identification is not its name. The computer name is useful for us. Moreover, this identifier must be unique.
