I'm working on a peer to peer network where we are having problems with email stalls. When a particular user checks their email at the remote email server---there is a connection and it just stalls. In Outlook Express it says connected and then just sits there. I've run a lot of plots from two different machines to see if there is a clue in them. Here is a 24 hour snapshot from one of the machines that has problems--I have multiple time windows on this same setup. The problem is very intermittent---most of the time it works fine or if you wait a bit and come back it's ok.

Thanks for the help,
Rusty
