My MacPro Keep's Renaming itself. HELP!!?

[jfriedman8]

This is really weird/annoying and I do not want to have to do a reinstall untill SL comes out, but my MacPro keeps renaming itself. Every time I restart or shut down recently it goes from "Jason's Mac Pro" to Jason's Mac Pro (2) to Jason's Mac Pro (3) and so on.
How do I make it stop!?

I had a similar problem after upgrading my router. It started acting up when it said the original name was already on the network and it snow-balled from there. This is what worked for me. Try resetting your router and wait until it's fully up and then go into system preferences and manually change the name back to the original. Here, at least, it started working normally again thereafter.
