Hi,

I am the tech coordinator for a small school district of 220 students. WE have two T1 lines to our ISP (the state of Wyoming).

From any computer on our network, we can connect to the internet, but not stay connected (times out after 2-3 min of connection, regardless of what you are doing).

The interesting thing is, when we do a web-ex, timbuktu, or similar session, we dont get timed out (kicked out) of those sessions. The connection stays active, even during one recent 8 hour web-ex session. I think this could be a key, but as I'm brand new in the district (and so is the other I.T. guy-we are not sure).

We have looked at our DNS config, router configs, etc., and had two different nextwork engineers look at our district, both cannot find the problem. I'm putting it out there to this community.

We can ping out, to other devices...and "see them". This started in July....and school starts on Wednesday. We can send a tracert out, and it goes.

We are not sure if there is a machine onthe network broadcasting something, we've reset all of our switches...we've taken our spam and internet appliances off, to see if while filtering traffic they were interupting someting, but we still have a problem.

Thanks for any suggestions.
