altering network setings via java program

Question

I want to write a program that will reset a user's Local Area Network / (TCP/IP) Properties.

Here's what I do manually (which I want to program to do automatically):

1) START -> Run -> cmd (get command prompt)
2) ipconfig /release
3) START -> Connect to -> Show all connections
4) Right-click "Local Area Network" and click "Properties"
5) Highlight "Internet Protocol (TCP/IP) and click "Properties"
6) Check box "Use the following IP Address"
7) Enter "111.111.111.111" for IP address
8) Enter "255.0.0.0" for Subnet mask
9) Click OK, and Close.
10) Wait 20 seconds
11) START -> Connect to -> Show all connections
12) Check box for "Obtain IP address automatically"
13) Click OK, and close.
14) Wait 20 seconds.

Answer 1

You appear to be trying to renew your IP address using DHCP.

Instead of writing a Java program, write the following batch file:

ipconfig /renew

Answer 2

Only through Runtime.exec (as SLaks mentioned) or using JNI. There is no native JAVA library which is capable of handling this issue as far as i know.
