Red X in network icon

All of a sedden a red x appeared on network icon om my wife's computer. It is running windows 7 pro 64bit. It still has internet and network acess. I can acess the other two computers on network from this computer. When you point to icon it says network and internet. But if you go to customize notifications there it says not connected to network or internet even though it is. Also if you go to sharing center it does not show local area connection like it does on my computer also running windows 7 pro 64bit. I have updated driver and released and renewed ip address but still have red x on network icon. It has not really affected anything other than I know it is not supposed to be there. Any help will be greately appreciated.

Thanks Shawn

for your reply but have restarted a dozen times.

I have read many ideas about this and have tried several with no luck.

Thanks again

I cannot find network and internet in control panel I have networking and sharing center and when I go there local area connection is not there. I will try to reset icons and let you know if this helps.

Thanks
Mike

I tried resetting notifications no luck. Also I created the network connections shortcut and when I go to it at top it says Control panel<all control panel items<network connections but it is blank nothing there.

Thanks for your ideas if you think of anything else let me know. I have 2 computers hooked up to same router wired and one laptop all running windows 7 and this is the only one that I am having this problem with. It goes online and I can see other computers when I go to network it just has the red X on the network icon.

Again thanks

Mike
