OT 'denial of service' attack
We were hit with such an attack a couple of weeks ago. It was kind of clever although I don't understand exactly how it was done. Someone sent in a mail message to a legitimate e-mail address but they somehow had a mailing list for the whole company appended in the auto-reply feature. Everytime someone read the message it would send another copy to the whole mailing list. It didn't take long for the mail system to get clogged up. I think IT had to write some quick filters to discard messages with the matching content.

Hi Rudy,..Re:.. There are lots of other potential bottlenecks, the net is 'non-deterministic' (you can't guarantee response time).

Several months ago, when fighting with DLJ about their connection time, I had to trace the routing to verify that the actual connect time was milliseconds which clearly demonstrated DLJ response time was the culprit. To do this, go to dos and at c prompt, type in 'tracert' space then the "IP address" you want to trace. Also, another problem can be caused by buildup in temp files in cache. Once a month, I usually clean the whole thing out.

Just some other possibilities,

Lee

OT - Rudedog, I don't think the problem is my ISP. All other sites I try are OK. If I go to www.techstocks.com (the site for non members), it's just fine. I have SI (for members) bookmarked as www.exchange2000.com, though on SI's front page it says talk.techstocks.com is the link. Doesn't seem to matter though. A tracert from DOS suggests a possible routing problem with "sprintlink". Seems there is squat I can do about it.
