I've been connecting my notebook computer running Windows
XP Home to my network at both work and home. It has
worked OK for over a month until I went in this week and
connected to the network at work. When I booted up
connected to the network, I got an hourglass over the task
bar/start button than I could only get rid of by killing a
svchost.exe process under the user name LOCAL SERVICE from
the Windows Task Manager. I've been unable to get
Tasklist /SVC to list what's causing the lockup. Once
this happens it continues every time I reboot. If I don't
kill it soon enough it starts repeatedly popping up and
disappearing on the Windows Task Manager with no ability
to kill it.

I restored the computer from a backup and it worked at
home. But, when I booted up on the work network the
problem repeated itself.
