I've solved the problem once, I've restored to recreate and i'm in the middle
of trying it again (sucker for pumishment). I disable comm and application
in msconfig.
Then i turned of fast switching. Restarted. Renabled com and applications
then tried to turn on fast switching, this prompted me to disable offline
file sharing.
That done everything worked ok again. The file sharing must have been
something to do with an attempt at setting up a home network I had recently.
