Which Windows utility provides information about current network connections on the network adapter?

The utility that provides information about current network connections on the network adapter is NETSTAT. This command-line tool is commonly used in Windows and other operating systems to display various network-related information. Specifically, NETSTAT can show active connections, listening ports, and various network statistics which are crucial for diagnosing network issues.

When using NETSTAT, users can see details such as the IP addresses and port numbers of all active connections, the status of those connections, and how long they have been established. This information is vital for network administrators and security professionals when assessing network traffic, identifying unauthorized connections, or troubleshooting network connectivity problems.

The other options, while related to networking, serve different purposes. For example, NET SESSIONS is used to display information about sessions on a server in terms of shared resources, while NET USE establishes connections to shared resources on a network. NET ACCOUNTS, on the other hand, manages user account policies on local or remote systems, rather than network connections. Thus, NETSTAT is the appropriate tool for obtaining detailed information about network connections on the network adapter.
