K, i gotta go anyways. Here is one last thing that just came to mind

You need to have a user account for the XP machine on the Vista machine and the Vista machine on the XP machine.

Add a user on each machine for the other one.

Start -> Control Panel -> 'User Accounts and Family Safety'.

The first selection in User Accounts and Family Safety is Add or Remove User Accounts

Thanks again BD, but I don't think that is the issue here. My XP laptop does not have any extra user accounts for the desktop, nor did I add any to the desktop for the XP laptop. Yet they share files without a problem.

Any other ideas? Anyone?

Thanks--

k, sorry I couldn't get you up and running

I found this interesting on the Microsoft site.

If the shared folder is on a computer running Windows Vista that has network discovery enabled, it should appear in the Network window quickly. If the computer containing the shared folder is on a computer running Windows XP, it might take up to 15 minutes for the computer to appear in the Network window.

Thanks again BD.

Is there any other information I can offer you guys? I feel I must be missing something small and obvious. Please help me out if you can; I really need to get this fixed ASAP, tonight if possible.

Many Thanks.

Can anyone help?

Did you ever check the Windows XP machine that you have the Link Layer Topology Discovery (LLTD) protocol installed on the machine. You can download the Link Layer Topology Discovery Responder from the Microsoft website

Hey BD- good to see you back

Yes, I installed the LLTD yesterday.

Is this thread in the wrong forum perhaps?

honestly I would start a new thread because this one is so long, thanks to me, people are not going to want to read through everything we just tried.

And I would change the title to 'Vista computer cannot share files with XP computer on home network'

With that being said I did find a great site with lots of information for you

Thanks BD, I do appreciate your help. I'll take a look at that link, and post another thread later.

Thanks again

There is a section titled networking and storage that might be better suited than windows OS
