Sorry, an error occured while reconfiguring TCP/IP. The connection file “^2” could not be found. The “Connect automatically, using Apple Remote Access” option requires that you select an Apple Remote Access connection file. ^1 Saving the changes may interrupt any TCP/IP services currently established. This control panel can't be used because TCP/IP is not installed. The control panel cannot be opened. The file “^1” could not be opened because it is locked or being used by another application.
