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. Doin...

To design and build a two-tier campus network architecture is everything like a three-tier hierarchical design and maximizes performance, network availability, and the ability to scale the network design. It is common to campus networks where the aggregation or distribution layer is merged with the core layer to create a unique and fully functional network for a good sized campus. However, many small enterprise networks do not grow significantly larger over time. Therefore, a two-tier hierarchical design where the core and distribution layers are collapsed into one layer is often more practical. A “collapsed core” is when the distribution layer and core layer functions are implemented by a single device. The primary motivation for the collapsed core design is reducing network cost, while maintaining most of the benefits of the three-tier hierarchical model.. To design and build a two-tier campus network architecture, a number of considerations must be taken into account. A k...

NTLM, a Windows network authentication protocol, is a challenge/response system that allows a client to prove its identity without sending a password to the server. The Windows domain controller challenges the client to perform a complex mathematical calculation on the user's domain password and send this encrypted password to the domain controller. The domain controller then uses the same calculation to decrypt the password. If the decoded password matches the password obtained from the Security Account Manager (SAM) database, then the client is authenticated and may log into the network and access network resources. NTLM is an abbreviation for Windows NT LAN Manager; it offers improved security over the now-obsolete LAN Manager protocol. The Indiana University network is configured to use only the latest version of this protocol: NTLMv2. This version provides increased security over NTLMv1. A Real Time Communication (RTC) application may specify RTCAU_NTLM in the tag t...

Internet security has a pretty high priority in our technology filled world. The safety of your private information and the safety of your computer should always be a primary concern. Browser-based email providers, such as Yahoo!, AOL and Hotmail, have spam and junk mail filters to keep your privacy and computer safe. By viewing the spam or junk mail settings and filters your email provider has in place, you can find out your level of security and make adjustments as needed. Step 1 Open your Web browser and go to the webpage of your email provider. Step 2 Log into your email account. Step 3 Find "Settings" or "Options" on the main screen of your email page. Typically, this is located on the right-hand side towards the top. Some email services have it located on the left. Step 4 Select "Spam" or "Junk" mail settings from the Settings or Options menu. Step 5 View the filter settings if they are available from your e...

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...
