If you use the second method, then add the username and password that you log on tot he other mahcine to the one that you can't access.
example if you log on to machine #1 with
username: user1
 password: 123
then add to machine#2
username:user1
password: 123
give them the appropraite permissions to the share(s)

Hi,
I just read some of your comments to the question "Windows XP Home computers not seeing XP Professional or 98 computers".

1. When I put that "Use simple file sharing" on -> I could access to the computer but it asked me User name and Password.

2. When I enabled Guest mode from Computer1, I could access to the computer and I see those shared folders (Computer1 didn't ask me any User name or Password), but I couldn't access those folders.

3. When I added Everyone to the both folders Security tabs "Group or user names" window -> now I can access to both folders without user names and passwords.

I did also that Sharing mode change to the Computer1. I also read that document behind link you gave me, but well... I don't quite get what I should do with those passwords and so on... When I looked that "Sharing and security model for local accounts" from Computer2 it was Guest only mode.

So basically, I can now access shared folders in both computers (without User names and passwords) but should I still put on some features? I guess security level of the sharing isn't the best possible at the moment...

Yes, well I trust both machines in my network. The reason why I'm worried is that Computer1 is attached to company intranet with ADSL-connection and through that to Internet (my two computers are attached to each other with WLAN access point). Company network is of course protected against outside world with firewalls but company network itself is very big too, so I would like to protect my computer against it too.

I have Zonealarm installed to my computer and my own intra has been configured as trusted zone.  I guess I don't have so many worries any more, but somehow I don't always trust those personal firewalls and I have always thought that these "share"-things are definitely the things one should avoid...

So if you just would briefly explain me some things:
1. What is the difference between Classic Mode <--> Guest only (like I'm three-year-old...:) ?
2. How can I add those user permissions so that only other computer can access to shared folder?
3. Why in my other computer there isn't Administrative tools in Start menu?

Thanks for you answers!

1. In classic mode, the users are authenticated as themselves, in guest mode they are authenticated as a guest, and only have guest priveledges, even if they log on with a username and password that is on the machine.
2. you need to add the user from machine #2 to mach#1
see the example above
3. go to control panel, admin tools, you can access them there. there is a setting to add them to the programs menu
right click on an empty area of the task bar and choose properties, start menu, customize, check show admin tools

Hi

I think you net to install NetBIOS Protocol in both computer, my best guess one of you computer hasn't  got  NetBIOS installed

How do do this GOTO Control Panel --> Network Connections -- Select the Local Area Network Connection Properties by Right-Click on the Connection icone, Then click Install Button Under the Heading General Tab "This connection uses the following items" Select Protocol and install The NetBIOS related item

thanks
Cedric

Cedric, just an FYI. You can't install NetBIOS, you can only enable it. You can install NetBEUI, but they are not the same thing. for the difference see here
