I am not sure if this has been asked before but searching couldn't find anything. I have a MacBook using Parallels and a direct internet connection (ethernet) using DSL. When I load up Parallels I get a constant Mac Dialog box saying: "IP Configuration 18.104.22.168 in use by <MAC ADDRESS>, DHCP Server 192.168.0.1" And I hit ok, but it keeps popping up. Obviously what is happening here is that the IP addressed assigned to this computer is trying to be used by both the Mac OS and Parallels and a conflict occurs. Please Help! I don't know how to solve this.
