100% CPU usage at startup

One of my laptops (XP SP3) runs slowly and shows absolutely flat 100% CPU
usage in TaskMan if it's started with networking enabled. It makes no
difference if it's connected to the router wirelessly or via Ethernet.

Disconnect the network, and the usage drops to a few percent in seconds.
Reconnect; it remains OK, there's full network functionality, and performance
is normal. My other laptop, running Vista SP1, shows no such problem which I
therefore assume is local to the XP machine. I can't see a substantial
difference to the processes that are running in either state, but there's a
lot of them and the list jumps around a fair bit, so I can't be certain.

I'd be really grateful for any pointers...

Hi
Look at the Start-Up and see if there is applications that you do not really
need at the Start-Up, and take them out.
Also make sure that you do not have mapped drives that are not existing any
more (if you do Unmap them).
