How do I reconfigure NTLMv1 on my computer ?

f you are running Windows, then this is the page for you. If you are running some other OS, then you’ll need to review NTLMv1 Removal – Known Problems and Workarounds instead. You will need admin privileges on your computer to make some of these configuration changes. If you don’t have those privileges, then ask your IT support to make this change. You can send them a link to this page. If your computer is part of a Windows domain, you may need your IT support to make this change–they may have implemented something that overrides any change you make. There are two types of changes your computer may need: one affects your Windows operating system and the other affects your browser(s). There are separate sections for each of these changes. Let’s fix up your operating system There are multiple ways to make this configuration change. We’ve listed all the ways below. You only need to pick one. We’ve ordered the easiest ways first, and labeled those methods appropriate for IT support

What Are the Challenges for Today's Network Administrators?

Today’s data center managers have been tasked with doing more with a smaller hardware budget. Networks are overburdened as a new flood of data from IoT devices have begun streaming in from every corner of the globe. According to McKinsey, the total IoT market size will grow to $3.7B in 2020, attaining a 32.6% CAGR. Network administrators have always been part hardware troubleshooter, cable slinger, and monitor of data. Now a network administrator must manage technologies that didn’t even exist a decade ago. We’re managing everything from teleworker connectivity and BYOD, to corporate networks to IoT and wireless access. Not to mention security across all these access points. What’s changed is our reliance on data centers as the backbone of our digitally obsessed society. The goal of the network administrator is still high availability, where users experience continual access with no network failures from hardware, software, or security breaches. Today, moving network data optimall

How to protect your network against security flaws in Microsoft's NTLM protocol

Vulnerabilities in NTLM recently discovered by security provider Preempt could allow attackers to remotely execute malicious code on any Windows machine or authenticate to any web server that supports Windows Integrated Authentication. Microsoft's NTLM (NT LAN Manager) is an older and now outdated security protocol that authenticates user credentials in a Windows domain. Though Microsoft has long since replaced NTLM with Kerberos as the default authentication method for Active Directory, the company still supports the older protocol, while recommending that customers adopt Kerberos instead. As we all know, even though a technology or protocol is old, outdated, or no longer recommended, that doesn't mean organizations no longer use it. The problem is that NTLM is continually plagued by security holes. In a report released on Tuesday, security provider Preempt describes the latest flaws and offers advice on how to protect your network against them. In its report, Preempt

problems faced by local area network engineer

Today’s networks need to support more traffic than ever. Employees access corporate data from desktops and mobile devices. Internet of Things devices proliferate everywhere on premises. Network designs and support strategies need to be adjusted to tackle these top challenges: 1.Poor network performance. There’s no question that poor network performance is a top challenge for network engineers. There isn’t simply more total traffic; there’s more traffic in all directions. Without the right equipment at endpoints and midpoints along the way, it’s impossible to provide the high-speed communication needed by today’s applications. Plus, performance isn’t just about speed; it’s about reliability, too. Network designs need to handle spikes in load and provide alternate routes to enable communication to continue even when a link fails. 24×7 online business requires 24×7 network availability. 2.Security. Security is another top challenge. Because the perimeter of today’s network is unclear

what is LAN ?

A local area network (LAN) is a group of computers and peripheral devices that share a common communications line or wireless link to a server within a distinct geographic area. A local area network may serve as few as two or three users in a home-office or several hundred users in a corporation’s central office. Home owners and information technology (IT) administrators set up LANs so that network nodes can share resources such as printers or network storage. LAN networking requires cables, switches, routers and other components that let users connect to internal servers, websites and other LANs that belong to the same wide area network (WAN). Ethernet and Wi-Fi are the two primary ways to enable LAN connections. Ethernet is a specification that enables computers to communicate with each other. Wi-Fi uses radio waves to connect computers to the LAN. Other LAN technologies, including Token Ring, fiber distributed data interface (FIDDI and ARCNET lost favor as Ethernet an
