Show Interface configuration

netsh interface ipv4 show config

Only IP Addresses of all LAN adapters

netsh interface ipv4 show address

Show global TCP/IP Parameters

netsh interface ipv4 show global

Disable and enable a Interface

netsh int set int name="ethernet" admin=disabled
netsh int set int name="ethernet" admin=enabled

Show all network interfaces and its link state

netsh interface ipv4 show interfaces

Print the routing table

netsh interface ipv4 show route

Show all tcp connections

netsh interface ipv4 show tcpconnections

Which Multicast groups are joined

netsh interface ipv4 show joins

Show dynamic portrange for outgoing connections

netsh interface ipv4 show dynamicportrange protocol=tcp

Set a static IP Address (172.16.254.2), Subnet Mask (255.255.255.192) and Gateway (172.16.254.1) on a specific interface (Local Area Connection 2) persistent

netsh interface ipv4 set address name="Local Area Connection 2" static 172.16.254.2 255.255.255.192 172.16.254.1 store=persistent

and temporary up to the next reboot and the parameters at full length. After the reboot the IP Address is empty.

netsh interface ipv4 set address name="Local Area Connection 2" static address=172.16.254.2 mask=255.255.255.192 gateway=172.16.254.1 store=active

Set DNS Servers without a DNS check, the set dnsservers command supports only one server as argument

netsh interface ipv4 set dnsservers name="Local Area Connection 2"  source=static address="172.16.254.250" validate=no

you have to add a second DNS Server with the add dnsservers directive

netsh interface ipv4 add dnsservers name="Local Area Connection 2" address="172.16.254.251" validate=no index=2

Set IP Address assignment on Interface to DHCP

netsh interface ipv4 set address name="Local Area Connection 2" source=dhcp

and also the DNS Servers

netsh interface ipv4 set dnsservers name="Local Area Connection 2" source=dhcp

Add a route for subnet 172.16.1.0/24 over interface “Local Area Connection 2” and router 172.16.254.254

netsh interface add route prefix=172.16.1.0/24 interface="Local Area Connection 2" nexthop=172.16.254.254

Note: Since Windows Vista its not possible to set the dns search suffix with netsh, you have to use WMI for this. To set the DNS search suffix use powershell and wmi. Define your Domains

[string[]]$aDNSSearchSuffixes=@("subdomain.domain1.local","subdomain.domain2.local")

Get the WMI Class to invoke the static method SetDNSSuffixSearchOrder

$oNetworkadapterConfiguration=[wmiclass]"Win32_NetworkadapterConfiguration" $oNetworkadapterConfiguration.SetDNSSuffixSearchOrder($aDNSSearchSuffixes)

Or invoke the method directly by calling the Invoke-WmiMethod commandlet

Invoke-WmiMethod -Class Win32_NetworkadapterConfiguration -Name SetDNSSuffixSearchOrder -ArgumentList @(@("subdomain.domain1.local","subdomain.domain2.local"),$null)

or

Invoke-WmiMethod -Class Win32_NetworkadapterConfiguration -Name SetDNSSuffixSearchOrder -ArgumentList @($aDNSSearchSuffixes,$null)

Note: If the aDNSSearchSuffixes Array contains more then one element a second parameter of $null is requiered otherwise the Invoke-WmiMethod command failed with error: Invoke-WmiMethod : Unable to cast object of type ‘System.String’ to type ‘System.Array’.
