We'd like to announce that we are opening a Network Monitor forum on TechNet. We also have forums hosted on Connect.Microsoft.com, but these are focused on our betas. We'll answer questions about filtering, using the Network Monitor API, writing parsers with NPL, the UI, reassembly, capturing, and anything else you want to discuss.
