I've got a number of local accounts set up on my machine (running SP1). When I login, windows accepts my password but doesn't load the task bar or desktop. All I get is the standard blue wallpaper. I can hit ctrl-alt-delete to pop up the security box which confirms I'm successfully logged in. But the desktop doesn't load.

I've trawled through the knowledge base but drawn a blank. Would be interested to know if any one else has suffered this and has a solution.
