I want to install SurfControl's Web Filter on my network, but have
realised that it only tracks IP addresses of machines rather than account
user names.

I know that the usernames of people on the network can be retrieved using
Enterprise User Modelling (EUM), but this means that if a user logs on to
a different machine the wrong user name will appear.

So my question is, is it possible to track users web access from an NT
Profile perspective rather than a machine IP perspective?

Many thanks
