Whenever I turn on my computer lately, I get a window that goes on about Restoring Network connections.

 

Says its restoring connection to, and gives a sharename.

 

And it goes on about Enter Network Password.

  Incorrect password or unknown username for

 

And then it lists one of my sharenames.  I have many shared folders on the network. Windows has never bothered me before about them.  Right now, it always asks me for the password for this other computer. Every time I turn on my computer.

 

Can someone help me diagnose this?  What could be happening special just when I turn on my computer?
