Server Is Busy

I have a laptop and all of a sudden when I am using it I get this little box that appears on the screen with this message " This server is busy, you can hit the retry button or switch to button" What is causing this and why?

 

It might be possible that the MSBlast.exe worm would cause that message so you need to get current virus def files for your AV (yesterday or today's version) and scan your PC.

If you are virus free, look in your event logs for an error or warning that matches that. Open the event and click on the icon below the up/down arrows to send a text copy of the event to your clipboard.

Post the event here.

Too many possibilities from the brief error you are seeing.
