[AccessD] [dba-VB] [dba-SQLServer] HELP, server completely unresponsive

What! That is so weird.  You  know that in Access we have the Do Events to
release the processor back to windows to carry out stacked processes waiting
to be actioned.  Well, I was wondering if *something* is not releasing the
processor but doing nothing itself.  Maybe on a timer tick over.

Post the problem to sqlcentral.com and see what come back.

Max,

That is exactly the problem, NO process is taking the ticks.  Often even SQL
Server is not taking 
the ticks.  The CPU usage is almost zero, but the cursor won't move, Alt-Tab
takes 15 seconds before 
it switches and even thin it is more seconds before the screen redraws.  It
is like Windows 
executive itself is out to lunch.

This is the strangest thing I have ever run into.
