Hi I had been using Windows at my work Network and I recently asked the IT support to change my OS to ubuntu. They have installed the OS but I am not able to connect to the wired internet. The output of ipconfig/all is:

ipconfig /all

I have replaced the numbers with 'x' for security purpose.

How do I configure these details in Ubuntu? Especially the Primary DNS suffix? I believe if I do that I might be able to connect to the internet.

I managed to get the network working by installing cntlm and configuring it.

You need to enter the password in cntlm. Setup your ubuntu proxy to the cntlm listen port. Then restart cntlm. You are set! You get networking for all your applications.
