Okay, now I'm just confused. I'll answer first the question that I understand best. I am using Windows 7 Ultimate x64, and am trying to connect to the shared drives with an Ubuntu Linux (Lucid Lynx) system. When I had things running before, I had to enter no special commands at any time. It was all done through the GUI on the Windows machine.
Now, when I enter that command, I get the following:
Microsoft Windows [Version 6.1.7600]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\Mollydog>net use * \\mollydog-pc\c$
Drive Z: is now connected to \\mollydog-pc\c$.
The command completed successfully.
C:\Users\Mollydog>
I have no idea what that did, or why you had me type it, but there you go.
Now, I am NOT using Homegroup. I do not WANT to use Homegroup. I do not know how, nor do I really care to learn how to use Ipv6. It's far too complicated for what I want to do, which is simply transfer files from the Ubuntu machine to the archives on the Windows machine without having to use a flash drive. When I connect to Network on my Ubuntu machine, I see "Windows Network," which I click to access. It then shows "Mollydog-PC" and "Ubuntu-PC." I click on the Mollydog-PC and it says I need to enter a username and password. So, I set up a Username and Password on the Windows machine. Still no access, it says invalid username or password.
I hope this information clears things up. If not, please tell me what else I need to add/do, and I will give it a shot. I have never had such difficulty in setting up my network before. I don't understand why it's such a chore this time. Thanks again for your help!
