It is possible that an intruder has compromised the machine on which you
were running powerpoint. This is one of the fields where windows really
excels - running stealth processes (back orifice, netbus, ...). What did
netstat -a on the windows machine say at the time? (Not necessarily the
real netstat anymore though...)

It is also possible that another machine on the same network is doing some
complex network sniffing and packet forging thing in order to impersonate
another machine (libnet is available for NT, AFAIK).

How to get an internal IP address? The IP address of the intranet machine
is often exposed by mail headers.
