I don’t think that I irrevocably damaged my girlfriend’s PC but I feel guilty about messing it up and I turn to other more knowledgeable Dopers to help me out.
I bought a laptop running Windows XP Pro and I have that one running on a small home network with 2 other desktops (I just can’t get rid of a faithful but slow PC!).
We had a great idea to connect my laptop to her laptop with a crossover cable so we could play PC games. Her laptop is for work, runs Windows 2000 and is connected to her work domain.
I ran the home networking wizards on both laptops and they still couldn’t recognize each other. After much tweaking I finally sealed my fate, I thought that the problem was that in the Connections tab, she was not a member of a workgroup but of her work domain. I removed her from her domain (big mistake) and added her to the MSHOME workgroup.
We still couldn’t connect. We gave up on the connection idea. She bought her own desktop anyways…
Here’s the issue. I wanted to undo all the damage I had done but I could not put her back on the original domain. She took her laptop back to work and had the IT try to guy do it. The IT guy says that he could not get the laptop to recognize the network.
Did I really mess up her PC? Can anyone give me a guide as to how to get the network to recognize her PC or is this an issue that you just have to know about the network configuration?
Also, are there any good resources I could learn about Windows networking?
