Free network IP scanners

30 septembre 2022 à 19:07

As hosts come online and go offline, there is a constant churn of hosts communicating on a local area network (LAN). Scanning networks with an IP scanner allows IT, network admins, and SecOps professionals to see which IPs are communicating and what types of devices occupy which IP addresses. It also helps to spot rogue, unsanctioned hosts that may be connected to the network. Several network IP scanners are freely available for download and help network administrators and IT admins discover devices on the network and manage IP resources. Let's look at the following tools: Nmap, Advanced IP Scanner, Angry IP Scanner, free IP scanner by Eusing
and the built-in command line and PowerShell.

Custom error message for access denied

27 septembre 2022 à 14:28

When you access a file share in Windows and the conditions for access are not met, you are normally presented with a generic access denied message. It is actually possible to customize the error message to provide more meaningful and understandable output that aids with dynamic access control, rather than the simple "contact your network administrator," which will invariably result in a call to the service desk. However, there are a couple of limitations to this functionality.
