Finder mounts a server upon startup

[wonder]

When I startup my Mac Pro, the finder will either connect to another mac I have in the office or try to connect to it and will give me a prompt that it can't connect (when the other computer is off). Somehow that's a default setting and I'm not sure how this happened.

How do I turn off this automatic mounting of this other computers HD onto my desktop?

I have no automatic Login items in my Sys Prefs under my account. There are no other accounts on this computer, FYI. I have also tried clearing the "recent items" in my Apple icon in the Finder.

I opened the console and notices a kernel that reads "disk6s2: device is not ready" ... I'm guessing that is referring to the computer that this Mac is trying to connect to but that computer is turned off. But, i can't figure out WHAT and WHY it's trying to connect to the computer.

ANY help is appreciated.
