Curl (client URL) is a command-line tool powered by the libcurl library to transfer data to and from the server using various protocols, such as HTTP, HTTPS, FTP, FTPS, IMAP, IMAPS, POP3, POP3S, SMTP, and SMTPS. It is highly popular for automation and scripts due to its wide range of features and protocol support. In this article, you will learn how to use curl in Windows with various examples. Let’s get started.

All Windows administrators need to know the essential concepts of Active Directory passwords: how passwords are stored in Active Directory, how password authentication works, and how to manage Active Directory passwords. A common task for admins is to reset users' passwords, which you can do with the GUI or PowerShell. However, in large networks, a self-service solution is required. Computer account passwords are another topic that administrators have to be familiar with.

You can use PowerShell to find and remove duplicate files that are only wasting valuable storage. Once you identify duplicate files, you can move them to another location, or you might even want to permanently remove all duplicates.

Secure Socket Layer (SSL) and Transport Layer Security (TLS, which builds on the now deprecated SSL protocol) allow you to encrypt Microsoft SQL Server network communication, which is essential for your security. In this post, you'll learn how to enable TLS on your SQL Server.

When Windows cannot load your user profile, you'll be logged in with a temporary profile. But if you see The User Profile Service service failed the sign-in. User profile cannot be loaded error after entering your credentials, it essentially means that Windows could not even log you in with a temporary profile. In this post, you will learn the causes of this profile load error and how to fix it.

Are you looking for a virtualization alternative to Microsoft Hyper-V and VMware ESXi? Proxmox VE is a Debian-based opensource alternative virtualization solution with a custom Linux kernel that you can use to virtualize bare-metal servers in your enterprise. It uses kernel-based virtual machine (KVM) virtualization technology for virtual machines and Linux Containers (LXC) for containers, allowing you to create and manage VMs, containers, storage, virtualized networks, clusters, and much more. This post shows how you can install the Proxmox Virtualization Environment (VE).

At some point, admins need to pick a suitable virtualization solution that best aligns with their existing server infrastructure. This post will focus on comparing three hypervisors: Proxmox VE, VMware ESXi, and Hyper-V.

IT admins or helpdesk teams often use graphical tools, such as Active Directory Users and Computers (ADUC), to unlock AD accounts. However, it is usually easier to unlock multiple AD accounts with PowerShell.

The post Unlock AD accounts with PowerShell first appeared on 4sysops.

In a previous post, we discussed how to quickly unlock AD accounts with PowerShell. However, the main problem admins tend to face is identifying the source computer or service that is causing the account to lock out in the first place.

In my previous post, you learned how to get started with Proxmox VE as an alternative to VMware and Hyper-V. In that post, I covered how to run your first Linux VM in Proxmox. Today, I will show you how to create a Windows VM in Proxmox. This may sound like a straightforward task, but there are certain settings in Proxmox VE that are worth checking out to make sure you get better performance in Windows. If you install Windows with the default Proxmox settings, you will likely experience poor performance.

The snapshot feature is available on every virtualization platform—whether you use Proxmox, Hyper-V, VMware or other virtualization tool. A snapshot enables you to preserve the state of a virtual machine, including virtual memory, virtual disks, and settings. Proxmox VE allows you to create live snapshots of the VM so that you can roll back to the point in time when something went wrong.

The post Snapshots in Proxmox VE first appeared on 4sysops.

The integrated backup feature in Proxmox VE allows you to perform a backup of selected or all VMs at once. Unlike snapshots, backups are independent copies of original data that can be stored either locally or remotely so that you can recover from almost any kind of failure.
