What Network Sniffing Tools Do You Use?

network-nose asks: "I work as a Network Administrator in a 500 user manufacturing facility in southeastern Wisconsin. My job is to keep the company running as close to 100% of the time as possible while trying not to spend any money on up to date hardware and software. As of late, we have been having quite a few network problems that can only really be resolved by sniffing packets. I am wondering what tools the rest of you network guys and gals out there use in a corporate environment for analyzing packets. Of course, the more reasonbly priced the better, but I know you usually get what you pay for."

I'm honestly a little surprised that a network admin (as the author claims to be) would post this question.

I'm not. It's not like you need to know the secret handshake before you can become a network administrator. In a lot of places, it just means you're the guy who knows the most about it.
