Network access validation algorithms

 If a client provides a LANMAN and an NTLM hash, only the NTLM hash is used unless the QZLSPWDANY$ share exists (or NetServer is configured to allow LANMAN authentication). This is because the NTLM hash is more secure. If only a LANMAN hash is provided (as was done by Windows 9x), that hash is used. NetServer does not support LMv2 hashes; therefore, LMV2 always fails. NTLM and NTLMv2 hashes are always accepted (with the restrictions in the table above) unless NetServer is configured for Kerberos-only authentication.

The QPWDLVL of the system does not affect the hashes that NetServer can accept. The thing that it does do is make the NTLM style hashes work with mixed-case Windows passwords. This is possible with QPWDLVL 2 and 3 because the system password can be mixed-case.

NetServer does not indicate to Windows to send a specific type of encryption. The only thing the server tells the client during the Negotiate is if extended security is supported by the server. The client will then try to negotiate whether to use Kerberos or password hashes. At no point does NetServer tell the client what form of password hash to use nor is there any way that NetServer could tell the client what form to use.

Free Windows Process Monitoring Software

 some tools are best fit purely for troubleshooting, but in the case of monitoring your LAN, a little bit of awareness can go a long way towards preventing problems before they happen.

There's a variety of software for monitoring your Local Area Network, both in terms of the devices attached to it as well as the traffic traversing it!

It's invaluable when trouble stirs to quickly discover the root of the cause, but there's more to it than just that – software with predictive alerts and monitoring can help you spend less time actively monitoring and more time focusing on other technical problems without sacrificing precious up-time

On a broad scale, LAN Monitoring software is great for keeping track of all the physical aspects of your network – the various devices connected to it, the servers that rely on it, the routing equipment that makes it function, and the systems that utilize it all.

Knowing a machine or server suddenly dropped offline as soon as, or even having it predicted slightly before, it happens is invaluable.

The happiest users are those who almost never realize anything is wrong because you're using the right software to predict and prevent problems as much as possible.

How can I remove old network connections

 Before we start haphazardly changing our Local Area Connection Properties, let's see what is the difference between enabling or uninstalling the connection properties.

Disable a Property Item:

Disabling a property item means it's no longer binded to the connection you're adjusting. This is the preferred method as opposed to full uninstallation since you can easily re-enable a property item if it's needed in the future - such as; you install a local network to share files from one PC to another and need File and Print Sharing enabled. If you just use your PC to access the Internet and never intend to create or join a network, consider uninstalling some items.

Uninstall a Property Item:

If you fully uninstall a Property item, the Windows queue will be reduced while accessing Internet routines. Admittedly, the speed increases of uninstallation versus disabling will be negligible. However, a property item may act as a filter or longer path for each Internet action, so there has to be something said for less computation (less error risk) while moving data to and from the Internet and your PC.

Everything You Need To Know About Internet Speeds

 It's often useful to test the speed of your local area network to ensure you're getting the amount of bandwidth that you need for various tasks. A LAN speed test can be useful in conjunction with an internet throughput test measuring how fast you can upload and download content from the internet at large or on its own to see how fast you can transfer files and data on your local network. You can find a variety of free apps to test the speed on your LAN.

Internet and LAN Speed Test

A local area network is a set of computers and other devices like smart phones and printers connected within a relatively small space, such as an office, a university or a home. A LAN can include devices connected wirelessly, ones connected by wired connections or a mix of the two.

Today, many LANs are also connected to the internet, and some are primarily set up simply to send local traffic to the world at large. But it's often also useful to send data between computers on a LAN, whether you're connecting to a network-enabled monitor for a presentation, storing files on a local server or sending print jobs to a printer on your network.

 The Quick Definition: Route redistribution is a process that allows a network to use a routing protocol to dynamically route traffic based on information learned from a different routing protocol. Route redistribution helps increase accessibility within networks.

What is Routing?

Routing consists of more than sending packets from one network location to another. The routing process also includes learning routes and determining the most efficient ways to handle network traffic.

Routers are configured in several ways that enable them to learn a route. The simplest method is to manually configure static routes. A static route tells the router exactly where to send packets. For example,  a static route tells Router 1 to route packets to Router 2, and then Router 2 is manually configured to send packets to Router 3.

The issue with static routes is that many routes change configurations — and the patch from one router to another often changes as a network grows. You can have thousands of different routes, and if one changes, you could be left manually configuring several routers. This can be a time-consuming process, especially when it comes to larger networks.
