I finally found the reason. I made a DOS boot disk, but it couldn't connect to the network all the time. Later, I finally found the reason. I installed an NT operating system, and found that this DOS disk can easily connect to NT, but it can't connect to 2000 and XP machines at all. My 2000 and XP have installed the NWLINK protocol. Why can't I access them? I have tried all methods. Why does this DOS boot disk use the NET USE command to access 2000 easily, but tells that there is no such resource when accessing 2000!!!?????????????????
