WindowsXP/2000: Using netsh

Windows XP

Reset the TCP/IP Stack
From a command prompt, type the following:

1. netsh int ip reset log.txt

Other Windows XP netsh commands include:

netsh diag connect mail
Will connect to the default incoming and outgoing mail server then drop the connection. Easier for customers than trying to telnet to the mail server ports

netsh diag ping dns
Will ping the default DNS servers progressively. (Saves having to re-type ping multiple times)

netsh diag connect iphost
Will make a connection to the host on the specified port, then disconnect. Example: To test http connectivity, type netsh diag connect iphost yahoo.com 80 will return

IPHost (yahoo.com)

IPHost = yahoo.com
Port = 80
Server appears to be running on port(s) [80]

netsh int ip show config
Shows the current IP address and additional config info

netsh int ip delete arpcache
Deletes the arp cache entries for all available adapters (including the dial up adapter) Works well with DSL if you are able to ping the loopback address, and your own IP but nothing else.

netsh diag gui
Launched the GUI Network Diagnostic Program

netsh diag show mail
Shows default mail servers

netsh diag show dns
Shows default DNS servers
