Question : Need counciling on modifying and saving files on a simple file-sharing network

Greetings wise wizards of EE:
Just recently, I have begun tinkering with setting up a simple file-sharing network with my home Dell Windows XP home desktop PC, and my HP Windows Vista Home Premium laptop PC. Both are able machines, with excellent hardware, connected to the network via an AT&T Yahoo DSL gateway.
With some research, and a bit of help from HP tech support, I've successfully set up the file-sharing network, but I keep running into problems when I try to open a file from another PC, and save it from another PC (i.e: When I open a file contained in my desktop FROM my laptop and then modify it, and then try to save the changes to the desktop FROM my laptop, I get a blue screen of death). I don't have any problems transferring files from one PC to another, but then I am entering the world of "too many file copies, which file is current". Is the ability of remotely opening a file and saving the changes to another PC too much to ask for a simple file-sharing network? Do I need a more advanced network to do this kind of thing, such as a server?
Please sing out with your wisdom. Many thanks,
Zovoth

Answer : Need counciling on modifying and saving files on a simple file-sharing network

Greetings EE:
After a great deal of experimentation and research on my own, I found the solution to my blue screen of death issue, when I tried to save files using one networked PC accessing another PC. It was a permissions issue, though I had to boot to safe mode to properly set the correct permissions. Here's what I did:
1. Booted to safe mode on the Windows XP PC that contained the files I wanted to manipulate
2. Right-clicked on the folders containing the files I wanted to open/edit/save and selected Properties
3. Clicked on the Security tab, and selected "Everyone". I then checked all of the permissions.
4. I then restarted normally, and that was it. From there, I successfully was able to open, edit and save files stored on my XP desktop, accessing them from my Windows Vista laptop.
There you have it. Now I'm going to Disneyland!!!
