Ever since our company moved to hosted exchange, there have been several lost connections with the exchange server per day, per workstation. As part of the hosted exchange move, they replaced our router with a Juniper router (won't let us have the user name/password).
Needless to say, there's a lot of "everything seems fine on our end" going on. Just this moning during a lost connection, one of our workstations got a strange "You are being de-registered due to network malfunction. If the problem persists please contact network support" message, seemingly from Outlook.
I am looking for a free/cheap network *summary* tool. Ideally, I'd just like to see a screen of "here are the IP addresses on your network, and here is the traffic volume coming from each device right now" kind of thing.
I need to be able to speak knowledgably to the hosted exchange company when they say, "Well, we see lots of traffic coming from this IP address through to the Internet..." and that sort of thing.
Is there a simple tool that provides this?
