Reliable and free network scanner to analyze LAN. The program shows all network devices, gives you access to shared folders, provides remote control of computers (via RDP and Radmin), and can even remotely switch computers off. It is easy to use and runs as a portable edition. It should be the first choice for every network admin.
This fast, highly configurable IPv4/IPv6 scanner can streamline many of your network support procedures. Its well-designed interface, light weight and portability coupled with an extensive range of options and advanced features make SoftPerfect Network Scanner an invaluable tool, whether you are a professional system administrator, someone providing occasional network maintenance, or a general user interested in computer security.
SoftPerfect Network Scanner can ping computers, scan ports, discover shared folders and retrieve practically any information about network devices via WMI, SNMP, HTTP, SSH and PowerShell. It also scans for remote services, registry, files and performance counters; offers flexible filtering and display options and exports NetScan results to a variety of formats from XML to JSON.
I have a WiFi-connected printer and scanner (Canon MG 5700) that I use from Windows 10. One of the nice features of Windows 10 is that I never had to install any drivers or bloatware to get it working. Windows automatically discovered the printer on the network, and it actually works.
Sometimes, it's a bit of a bother to have to reboot the computer, so I'm looking for a way to resolve the problem that doesn't involve a reboot. I've tried to close and restart the Windows Fax and Scan application, but that doesn't solve the problem. I've also tried to disconnect from, and reconnect to, the WiFi, but that also doesn't help.
I have an MG7150 and restarting the Windows 10 service Windows Image Acquisition (WIA) AKA stisvc did the trick. I had to restart it three times, so I guess some randomness is involved. The last time it refused to be stopped and I had to manually kill the process. To kill the correct svchost.exe process, add the Command line column in Task Manager's Details tab and find C:\WINDOWS\system32\svchost.exe -k imgsvc
The solution is really thanks to the comment by Thijs van Dien. Before I found that I had already tried several things. Including moving the printer to the wired network, but I don't think that makes any difference.
I had the same issue with an HP scanner and it was an IPv6 / IPv4 problem, try to disable IPv6 on the scanner and see if it works.When my PC tried to connect to the scanner with IPv4 worked fine but when it used IPv6 there was something wrong going on.Rebooting the PC flipped the coin between IPv6 and IPv4 and sometimes worked, sometimes not.
The Network device discovery and vulnerability assessments Blog (published 04-13-2021) provides insights into the new Network device discovery capabilities in Defender for Endpoint. This article provides an overview of the challenge that Network device discovery is designed to address, and detailed information about how get started using these new capabilities.
A designated Microsoft Defender for Endpoint device is used on each network segment to perform periodic authenticated scans of preconfigured network devices. Once discovered, vulnerability management capabilities in Defender for Endpoint provide integrated workflows to secure discovered switches, routers, WLAN controllers, firewalls, and VPN gateways.
Once the network devices are discovered and classified, security administrators are able to receive the latest security recommendations and review recently discovered vulnerabilities on network devices deployed across their organizations.
Network devices aren't managed as standard endpoints since Defender for Endpoint doesn't have a sensor built into the network devices themselves. These types of devices require an agentless approach where a remote scan obtains the necessary information from the devices. Depending on the network topology and characteristics, a single device or a few devices onboarded to Microsoft Defender for Endpoint performs authenticated scans of network devices using SNMP (read-only).
More networking vendors and OS will be added over time, based on data gathered from customer usage. Therefore, you're encouraged to configure all your network devices, even if they're not specified in this list.
Make sure SNMP read-only is enabled on all configured network devices to allow the Defender for Endpoint scanning device to query the configured network devices. 'SNMP write' isn't needed for the proper functionality of this feature.
To configure scan jobs, the following user permission option is required: Manage security settings in Defender. You can find the permission by going to Settings > Roles. For more information, see Create and manage roles for role-based access control.
The scanner has a scheduled task that, by default, is configured to look for updates regularly. When the task runs, it compares the version of the scanner on the client device to the version of the agent on the update location. The update location is where Windows looks for updates, such as on a network share or from the internet.
If there's a difference between the two versions, the update process determines which files are different and need to be updated on the local computer. Once the required updates are determined, the downloading of the updates start.
Enter the Target (range): The IP address ranges or hostnames you want to scan. You can either enter the addresses or import a CSV file. Importing a file overrides any manually added addresses.
You can select to Use azure KeyVault for providing credentials: If you manage your credentials in Azure KeyVault, you can enter the Azure KeyVault URL and Azure KeyVault secret name to be accessed by the scanning device to provide credentials. The secret value is dependent on the Authenticated Method you choose, as described in the following table:
Each scanning device can support up to 1,500 successful IP addresses scan. For example, if you scan 10 different subnets where only 100 IP addresses return successful results, you'll be able to scan 1,400 IP additional addresses from other subnets on the same scanning device.
Once the results show up, you can choose which devices will be included in the periodic scan. If you skip viewing the scan results, all configured IP addresses are added to the network device authenticated scan (regardless of the device's response). The scan results can also be exported.
Newly discovered devices are shown under the new Network devices tab in the Device inventory page. It may take up to two hours after adding a scanning job until the devices are updated.
Verify that the required URLs are added to the allowed domains in your firewall settings. Also, make sure proxy settings are configured as described in Configure device proxy and Internet connectivity settings.
Verify that the required URLs are added to the allowed domains in your firewall. Also, make sure proxy settings are configured as described in Configure device proxy and Internet connectivity settings.
If devices are still not shown, verify that the service 'MdatpNetworkScanService' is running on your devices being scanned, on which you installed the scanner, and perform a "Run scan" in the relevant network device authenticated scan configuration.
As the authenticated scanner currently uses an encryption algorithm that isn't compliant with Federal Information Processing Standards (FIPS), the scanner can't operate when an organization enforces the use of FIPS compliant algorithms.
How would I go about doing this? I did something similar recently on different network and it was my Windows 10 where I just run the tool Angry IP scanner where I gave it a range of IP and tool just run and showed me the results.
If you have duplicate IPs you will know. One device will get interrupted and/or prompted that there is a conflict. IP scanner applications only tell you which IPs are used but not duplicates. If you suspect there is a Device conflicting, check first the static IP devices are not inside the DHCP or make sure they have reservations in your DHCP server.
Since Windows 11 install, I can no longer scan from MF424 printer to my PC. Printer allows me to select my PC by name, but won't scan; after a couple of minutes gives "ERROR" without specifying the error. Using ScanGear from a 12/2021 driver downloaded from Canon.
It looks like the scanner is on the network but some of the software is missing on the Windows 11 computer. If you have installed a new version of Windows onto your computer, you will need to reinstall the drivers so the computer can properly connect to the scanner. When you send a scan to a computer, the computer will start the corresponding scanner software on the computer to process the scan. If the scans begins but does not process, you can try installing the Windows 11 version of the drivers. You can download and install the recommended driver found at the link HERE. Once it is installed, and it detect the MF424, you can try scanning again from the operation panel.
Thanks, but I had already done that and rebooted my Windows 11 PC. BTW, CANON website recognizes my OS as Windows 10 (64bit), in spite of its being Windows 11. The driver I downloaded works fine for printing. I confirmed that install software had installed scanner software. But I don't recall removing old scanner driver, figuring that the new install would take care of that as it had for the printer. ???
Our network gave an error that there was an IP address conflict and I'd like to find what all the device IP addresses are. (I've also had need of that before). (update/clarification:I'm looking for a Windows-based too.)
