Hi all,

I have 2 offices, A & B. Office A is the busier of the offices and also contains the company exchange server.

Both offices are linked via a VPN between two Firewall Fireboxes.
Last week I moved user accounts to a new email server and also upgraded the company Anti Virus software (McAfee to CA Etrust 8).
I started off by upgrading the antivirus software and then the mail server. Since I started all this Office B keeps losing internet access that can only be fixed by resetting the firebox. I've still to call the ISP to run a line check, however if it's not that then I need to diagnose what's bringing the office B network down. Can anyone suggest network monitoring software that could look over the entire network?

Thanks.
