Computer Name Change Issue

I'm setting up a new computer and copying files from the old computer over the network. In the meantime, I decided to change the name of the new computer. The new name appears but with an empty file folder. The old one also still appears but cannot be
accessed. I thought I could solve the problem by changing the name back to what was originally assigned, but that didn't solve he problem. Any suggestions on how to restore access to this computer on my network?
