forensics tools - preserving data?

[Dana Rawson <absolutezero273c () nzoomail com>]

G'Day All,

Before I begin, I wanted to thank everyone who had provided me with direction on my last post regarding pgp.

Hopefully I have as simple a question as before.

I have a client who recently had to terminate an employee and part of their decision was based on dereliction of duty.  
Basically too much time spent surfing the internet and not performing her expected duties.

They have asked me to gather the internet history, temporary internet directory files, etc.

I can pull up the files, archive them and explain the information to them.  But how do I go about extracting the 
information (i.e. The internet address of the many files that lie in the temp internet dir) so I am able to present it 
in acceptable fashion that they might use it in a court of law as evidence should it come to that.

I have been looking but can't seem to find what I think I need.  I have located tools on

 and see that NetAnalysis might prove useful but appears to be overkill.  Or is this exactly what I need?

Thanks in advance, again.
