And have a look in this Wiki page. 

Every PardusPC (that means a computer with Linux) should have a unique Workgroup and NetBIOS name in the network.
And when you have more than one PardusPC in the network and you don't change these values, they will all have the same name.
Maybe this is a better definition. 

As attachment.

Because of I expect the problem to be on the win-laptop side.
Did you use this manual?
What is the version of Windows on win-laptop?
Also have a look here #42 and here #46.

I don't have XP Home, so I can"t test this version. 

Thanks, somebody did find the ON-switch. 

is already "off the air" for this whole day !! :'(

Thank you, have a look in the wiki. 
XP Home?     I used WindowsXP Professional (+SP2).

Edit: Because I can't change post #31

At this moment I don't have any problems listening to Live365 in FF.

Here is my solution if you want a file manager with administrator privileges in KDE4.
In KDE3 I installed Krusader.
After this I switched to KDE4 with CTRL+ALT+F1 and
(sorry it's in Dutch)

In KDE4  ALT+F2  krusader +<enter>
In Krusader > Gereedschap (Tools) > Krusader in root modus starten.
And you can do the same as in dolphin or konqueror in root mode. 

As a result of this topic I have added the following new Wiki pages: 

Setup a fixed IP address for your computer
How to print in Pardus to a remote Pardus + printer
and to compensate for the long time to wait for them
How to access your files on a remote PardusPC

If you find any small/big errors or other remarks ..............you are welcome to report them in this topic. 

And a new call for somebody with an English XP version to have a look for the translation of the Dutch text in this Wiki page. 

Look here.
And I made a modification to the wiki.

Edit: Also look here and here.

The problem is in Samba.
After downgrading to samba-3.0.31-35-4.pisi the problem is gone. 
It is time for a bug report.
The protocol to transfer files is still working.
Only the part to change settings has a problem.

Samba seems to be working.
I can make contact and read/write with the remote side with:Try it.
I guess that the problem is in Tasma > Internet & Network > Samba
I think the communication between Samba and /etc/samba/smb.conf is the problem.
