Web Logon Prompt in ISA 2006

[flexyjerkov]

Righty...

I've tried google and had no luck so have thought to try on here.
Is it possible to force users to login to the ISA proxy server when trying to access the internet and is there any easy way to monitor user activity though logs?

Having the issues just recently with excessive amount of proxy bypassing though certain websites and need to find out who is doing it.

Thanks

I don't have ISA, but I assume you can require authentication, and use integrated authentication. Then if they're using IE, their current logon credentials are used.
My guess is there will be some free apps out there to sort through the logs, especially if you set it to log to an SQL database.
