Netsh diagnostic (diag) commands

This page is from Microsoft

Updated: January 21, 2005

You can use the Netsh Network Diagnostics commands, or diag context, to administer and troubleshoot operating system and network service parameters from the command line. The command prompt for the Netsh diagnostic context is netsh diag>.

The following commands are available at the command prompt for the context (as distinguished from the Windows Server 2003 family command prompt). The Netsh Diag context is new to the Windows Server 2003 family. You cannot run Netsh Diag commands on a Windows 2000 Server.

You can run these commands from the Windows Server 2003 family command prompt or from the command prompt for the Netsh diagnostic context. For these commands to work at the Windows Server 2003 family command prompt, you must type netsh diag before typing commands and parameters as they appear in the syntax below. There might be functional differences between Netsh context commands on Windows 2000 and the Windows Server 2003 family.

For more information about netsh, see Netsh overview and Enter a netsh context .

Syntax

The FullAdapterName parameter specifies the adapter by its name as registered in the operating system. The PartialAdapterName parameter specifies the adapter or adapters whose names contain the sequence of characters specified in the parameter. If the sequence of characters must appear at the beginning of the name, type an asterisk at the end of the parameter. If the sequence of characters must appear at the end of the name, type an asterisk at the beginning of the parameter. If the sequence of characters can appear anywhere in the name, type an asterisk at the beginning of the parameter and at the end of the parameter.
{ /v| /p}
Specifies whether fields with a null value should appear. The /v parameter specifies that the fields should appear. The /p parameter specifies that the fields should not appear.
