Ms lan manager software

LAN management tool for network operation Every organization's approach towards business operations is unique, and so is its network infrastructure. LAN inventory management OpManager maintains an inventory of all devices and interfaces in your LAN, and collects information such as IP address, DNS name, vendor, OS version, system description, monitoring protocol, device health, traffic counter, and more.

LAN configuration management A major threat to the stability of the LAN is a lack of details about configurations, since configurations ensure network devices function properly. Prevent attacks on your LAN Firewall monitoring and management A firewall protects your LAN infrastructure by blocking trojans, spyware, and other malicious programs, and is governed by specific firewall rules and policies.

Scalability: OpManager scales with your business needs. With OpManager , you can monitor 10 devices, devices, or even 10, devices based on your requirements. Support for multiple vendors: OpManager offers support for more than 53, vendor templates, so you can efficiently manage your LAN devices from vendors such as Cisco, Juniper, Fortigate, and many more.

These templates can also be customized to address your organization's unique needs. Prioritizing LAN faults: You can set multiple thresholds for performance metrics with different color codes.

This enables you to detect and prioritize LAN faults easily. Business Views can be created for critical business servers and services which help you pinpoint LAN faults and deliver unmatched services free from disruptions. Advanced LAN fault notification: In addition to providing LAN fault alerts in real time to the users, OpManager can notify a higher authority if they are not addressed promptly. Starting with Windows NT , it was replaced by NTLM, which is still vulnerable to rainbow tables, and brute force attacks unless long, unpredictable passwords are used, see password cracking.

NTLM is used for logon with local accounts except on domain controllers since Windows Vista and later versions no longer maintain the LM hash by default. The major weaknesses of LAN Manager authentication protocol are: [7]. On the negative side, the same DES algorithm was used with only bit encryption for the subsequent authentication steps, and there is still no salting. Furthermore, Windows machines were for many years configured by default to send and accept responses derived from both the LM hash and the NTLM hash, so the use of the NTLM hash provided no additional security while the weaker hash was still present.

It also took time for artificial restrictions on password length in management tools such as User Manager to be lifted. It has for many years been considered good security practice to disable the compromised LM and NTLMv1 authentication protocols where they aren't needed.

Many legacy third party SMB implementations have taken considerable time to add support for the stronger protocols that Microsoft has created to replace LM hashing because the open source communities supporting these libraries first had to reverse engineer the newer protocols— Samba took 5 years to add NTLMv2 support, while JCIFS took 10 years.

Poor patching regimes subsequent to software releases supporting the feature becoming available have contributed to some organisations continuing to use LM Hashing in their environments, even though the protocol is easily disabled in Active Directory itself. Changes to this policy become effective without a device restart when they are saved locally or distributed through Group Policy.

This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation. In Windows 7 and Windows Vista, this setting is undefined. Microsoft and a number of independent organizations strongly recommend this level of authentication when all client computers support NTLMv2.

One of the four panels of the Summary view includes a list of critical conditions that have occurred in the day. Live data transmission that feeds into this summary page comes from the SNMP methodology.

Most new network-compatible equipment comes with SNMP functions pre-loaded in the firmware and the SolarWinds Network Performance Monitor automatically detects and interacts with device agents to keep you informed of equipment status.

The interface can be customized to filter status alerts and notify different team members according to different network activity conditions that might arise. This helps you to manage your time more effectively if you are in charge of a large network, supported by a group of specialists.

The monitoring package manages wired and wireless networks. You can drill down to get details of each node on the network to examine problems and keep track of utilization. Again, the node detail screen has graphic displays to give you a full picture of performance at a glance.

Prices increase according to the number of nodes on your network. So, if you only have a small network and a very tight budget, this comprehensive LAN monitoring tool is probably not for you. That log of network equipment is constantly updated and it is also the source of an automatically drawn network topology map.

The system will continuously check on the availability and health of all network devices by using the Simple Network Management Protocol. OpManager is produced by ManageEngine , another significant player in the network software industry. You are allowed to monitor up to three devices with the free OpManager.

However, you still get the same level of system notification that users of the paid version get. The engine of the monitoring methodology uses SNMP. This is built into all new network-compatibility hardware, so you will automatically be able to get real-time feedback on network activity from all of the devices connected to your network.

Another common technology that underpins the OpManager system is the NetFlow traffic monitoring methodology. Whether you are using the free system, or if you have opted to pay, the software can be loaded onto Linux or Windows. If you are looking into buying the OpManager system, you have the choice of two plans: Essential and Enterprise.

You can manage up to 1, nodes with the Essential plan and up to 10, with the Enterprise package. Both of these options can extend their monitoring to WAN and voice systems with remote monitoring and QoS functions. This will map your network and present it in a nice graphic in the dashboard. The map displayed on the screen is based on a real map of the world , so you can get a visual representation of your entire network even if it is global.

If you are looking into buying the OpManager system, you have the choice of three plans: Standard, Professional, and Enterprise.

The Enterprise package is designed to monitor multiple sites from one central location. The more expensive Professional package includes extra features, such as automated and regular device discovery.

You can download OpManager on a day free trial. The underlying technology that drives this monitoring utility is the NetFlow system. This is able to track packet transfer rates around your network in real-time. A drill-down utility to get a look right down to the network protocol level is provided by a packet sniffer utility. The alerts provided by SNMP enable network administrators to stay ahead of crises. You can save a lot of money on your support desk if you can stay ahead of hardware failure and fix it before user calls start to get out of hand.

A great benefit of SNMP is that it uses very little bandwidth, so your monitoring with this suite will not slow the network down. The dashboard of the Paessler system is a great user interface that includes graphs, charts, and dials to give you instant information on the overall status of your network.

You can query individual nodes on the network to get instant status reports containing live data. Those device-specific pages contain easy-to-follow graphics and the whole dashboard can be accessed from any computer on the network as well as tablets and smartphones. PRTG is particularly powerful for multi-site operations that include internet connections and cloud services.

PRTG will also monitor your wireless networks. A lot of the installation procedures are automated and the integrated network discovery feature gets your topology mapped automatically.

The LAN monitoring tool includes templates that gather status information on each device. That brings a standardized format to your monitoring effort, enabling you to pay equal attention to all of the equipment on your network. Many aspects of the PRTG monitoring system can be customized, giving you the notifications and statuses that have become critical to the success of your network. There is also a freeware version — aimed at assisting small businesses as they grow — which currently allows for up to sensors to be used for an indefinite amount of time.

This pack is completely free of charge. Network performance monitors usually focus on the statuses of network equipment; network traffic analysis tools, such as this one, look at the volumes of traffic that pass along the network cable between devices. So you can get an understanding of the events on the cable by looking at the flows of traffic on the network equipment at either end.

It both duplicates traffic and calculates summaries of traffic types and volumes. The NetFlow Configurator acts as an interface to all your Cisco routers. NetFlow works on IP packet headers, so it is a relevant function of switches.

Rather than logging in to each router in turn and working through the router manager menus, you can just use this simplified front end that narrows down all of the functions to just turning on NetFlow capabilities and directing that traffic to your NetFlow collector.

This acts as a great time saver. This enables you to get a look at traffic in a replay. This saves you the worry of having missed the reasons for any slow down or failure that might have occurred while you were out of the office or away from your desk. The NetFlow Generator creates fake traffic to give you extra volume to run around your network.

This is a great exercise if you plan to increase services or add extra endpoints to your network that would result in greater traffic volumes. You can test the performance of your load balancers, firewalls, and network performance monitoring alerts before planned changes occur. The Flow Tool Bundle helps you head off disaster before it happens. The Flow Bundle is offered as a free utility. The Site24x7 Network Monitoring Tool is a comprehensive IT infrastructure monitoring system that also has application monitoring baked in.

Another module in the package tracks user behavior on websites and creates synthetic user walk-throughs for website testing. A major part of the infrastructure monitoring service is the network monitor. This is a network performance monitor that communicates with network devices rather than watching traffic as it passes over the cables of the network. This is a cloud service , so there is no need to install any system management software on-site.

The service connects to the monitored network over the internet. All communications between the network and the controller in the cloud are protected by encryption. Access to the dashboard, which is resident in the cloud, is facilitated through any web browser.

The data transmissions of this access are also protected by encryption. Site24x7 begins its service by contacting the monitored network and performing a system sweep. In this phase, the network monitor contacts every device for its identification details, including make, model, and statuses.

The results of these inquiries are written into an inventory. Site24x7 also creates a network topology map from the information gleaned during the autodiscovery phase.
