I have installed Kubuntu and I am having trouble changing the workgroup so I can see my Windows XP systems and share files and folders.

Hello and wel-come to LQ.

Can you please elaborate more?
How you change your workgroup and what error you face?

if you want to access windows share then you doesn't rwquire any configuration in linux.

if you want to share data from linux to windows then you have to configure samba.

Greetings.

If I understand your problem correctly you would like to change your current workgroup from whatever it is now on your linux box to one of y our choosing that matches the windows workgroup thus allowing you to access and see network shares within the workgroup.

Edit this file: /etc/samba/smb.conf

replace under the [global] section

workgroup = WhateverYouChoose

After saving that file you will need to restart samba. Two ways to do that depending on your system.

sudo service samba restart //this should work for you on debain based system

or

/etc/rc.d/rc.samba restart //this probably will not work on debain based system.

I hope this helps you.
