('binary' encoding is not supported, stored as-is) In-Reply-To: <20030125021141.A23211at_private> Michael, I feel your pain. I've seen the same thing starting at 12:46 AM EST 01-25- 2003 at one of our colocation facilities. I haven't had time to analyze things as of yet - I discovered three machines, all with activity that started at this same time, all running windows 2000 and SQL Server 2000. It crippled internal connectivity - basically, any machine that actively had this going on, if we would plug it into a port on an HP4000 switch it would freeze the switch instantly and then anything on the local network would suffer. I'm working on isolating these machines to a local segment and then putting them back online so that I may see what type of traffic is generated or received at brief intervals. I don't know what it is, but it's certainly detrimental to network performance!
