Monitoring website addresses, email, etc from Windows 2003 Server

Currently I have a client who is running a Windows 2003 Server with about 12 seats and 5 terminal licenses.

They are looking to monitor all internet related activities for each user account.

It is acting as:

- the file server
- primary domain controller (roaming profiles)
- DHCP server
- Name server (mainly relay to ISP servers)
- application server
- exchange server (mail)

What they are looking for is the best application to monitor all Internet related activities. I know some people are against this, but there is cause for this in the workplace as this workplace is a sensitive environment in terms of public appearance and porn popup ads are not good for business.

I hate to say this... but since you are already running on 2003... ISA Server will do exactly what you requested.
