After hours of trying to work out this problem, this is what happens now:
My Ubuntu machine display my 2 Vista computers, but when I click on them, I don't see any shared folders.
Needles to say that everything worked before I installed Ubuntu.
On the other side, I fixed the problem I had; The Vista computers now have full access to the shared folders on my Ubuntu computer.
Please help me fix this, because I really like Ubuntu.
Hmmm.. perhaps not the helpfull answer he was after Geeky, although +1 Spread the OSS word bonus.
Sorry but I'm one PC only here and no vista machines in the house so I can't test to provide insite. You might do worse that to take a look on the Ubuntu help forums as I'm sure others will have found similar situations and asked for help.
I configured shared folders on the vistas.
I have a wireless router and use samba.
I just tried something with Gutsy live CD.
I tried connecting the shared folders on my vista and it asked for user, domain and password. when I entered the information it worked.
so how do I bring back the auth. window?
Here's a quick one to try, I use it at work when getting my Ubuntu computer and Windows 2003 servers to play nice with sharing files.
Go to "Places", then click "Connect to a Server"
Change the publicftp to "windows share"
Put in the other computers IP address and share directory (if needed). Click okay, if you need authentication, the auth box will appear, add your username & password, clear the domain box and click save password forever (only do this in private use, otherwise anyone can dive into the other computer through the share).
I know on Windows XP sometimes you won't get the Authentication window if the guest user is turned on. Also, you might check the firewall on your vista computers, maybe try disabling it if you have it enabled. I had a share up and running before and 3 different Vista users were able to connect to it.
One last thing @ knightrous : if using Hardy Heron Ubuntu you will have to enter in the "optional" share name. Other wise you get the message "No application is registered as handling this file".
