You might want to acquaint yourself with The Most Misunderstood Windows Setting of All Time. It’s the best written document on the relevant background for LMCompatibilityLevel. Review the NTLMv1 Known Problems and Workarounds for the most comprehensive resource available for the various problems associated with NTLMv1 being turned off. Note that NTLMv1 use can result from misconfigurations in a great number of places. And those misconfigurations can happen anywhere in the “authentication chain”. Misconfigurations can happen on the client endpoint, on a member server that provides the service the endpoint connects to, or any domain controller leveraged by the two. Most misconfiguration comes down to one of two things: the Windows LMCompatibilityLevel or browser configuration. If you are looking for the quickest way forward, we’d suggest using group policy to set a LMCompatibilityLevel=5 (“Send NTLMv2 response only. Refuse LM & NTLM.”) across all your computers. Doing this will like...

In many cases, once a Wireless router has been installed, we find a place in our home for it and forget about it. As long as all our devices are set up and connected via the Wi-fi network, that’s all that matters, right? Wrong! Probably many of you don’t realize, but the Internet router is one of the most important devices in our home. It’s the gateway to our Internet access and also prone to exploits by cybercriminals who can sneak into our devices and get access to our system. Let’s not forget that we live in the age of data breaches, ransomware attacks, and many other online threats. Thus, you should be worried about the security of your home network and take all the needed security measures to increase Wifi security. The only measure most people use to protect their home network is to set up a password and prevent neighbors and other people from taking control of your data. But we have to be more serious about security and do more than just setting a simple password. A serious ris...

Networks are networks. Despite best efforts to keep things smooth all the time every day, things happen. Here’s a look at some common network issues, some tips for quickly resolving them, and even better, how to prevent them from occurring again. 1. Duplicate IP Addresses When two devices attempt to share a single IP, you see the dreaded “Address Already in Use” error — with no ability to access the network. The Quick Fix: The blame for this often rests with your router’s default DHCP configuration. DHCP is probably trying to assign your new device an address at the beginning of your subnet, and another device may already occupy these low-numbered addresses with static IPs. If you’ve just introduced a new device or server to your network, it may have its own DHCP server. Simply disable the DHCP server on that device to restore sanity to your network. The Preventive Measure: You can take one simple step to avoid IP conflicts by modifying your router’s configuration to begin assigning D...

The art of networking is no easy feat. And as networking jobs encompass more than just networking, it’s not going to get any easier. It’s going to be about embracing advancements in data gathering, automation, and programming languages. In fact, it’s going to look a lot like DevOps. Here are five skills you can develop to meet the changing tides of the networking industry. Learn a Language It never hurts to learn a new programming language. To keep up with automation, network engineers need methods and tools to programmatically control equipment. This is where languages can come into play. If your organization is using software-defined networking (SDN), keep in mind the networks offer interfaces to scan and monitor automatically. Fully understanding the language these programs are speaking gives you an upper hand. Automation tools like Chef can handle some of the grunt work, freeing up time for your networking pros. But admins should still understand the process of writing their own s...
