Something like Ethereal would be a good utility to start with. You will need an old-school hub somewhere in the pipe between your sonicwalls and the rest of your network to monitor traffic tho. Since we are just talking a T1 you can use any old 10-base hub laying around. Also might be a good idead to get a dedicated machine cause it is not always stable
Finding a network problem is always fun. That is an excellent suggestion!
Using an old school hub which broadcast a mirror every packet to each port instead of placing an old and unstable computer between the Sonicwall and the network would be ideal!
By the way, I found one of the problems was actually with our local name server.
So basically it was not translating a website into an IP address and just freezing up on everyone.
So it would give you a timeout error when you type in a web address however if you typed the IP address directly, it worked fine.
Once the name server was setup on a new computer, everything started to work great again.
So there is 1 network problem solve but still a lot more to go such as the point-to-point sonicwall tunnel.
Everyone always seem to point to the T1 whenever there is a problem instead of looking at network configuration issues and monitoring bandwidth.
Thanks for your help!
