Terminal cannot kill systemUIServer process, and systemuiserver.plist file does not exist on my macbook.
I thought you said this is the first thing you tried above?
The com.apple.systemuiserver.plist is in your user folder ~/Library/Preferences/ com.apple.systemuiserver.plist
The ~/Library is hidden in Lion however Finder>Go (dropdown menu) hold the option key to see the ~/Library
Terminal cannot kill systemUIServer
This is not correct command line, unix is case sensitive, it should read:
killall SystemUIServer
Short of this I would consider backing up and re-installing the OS X Lion if problems persist.
