Hi, Heath, Thank you for your message. I don't think I am running any type of DNS server on my machine. Also, I don't think it is DNS related problem since when I tried the real IP address, it is not going through either.
You are right, the machines that I have no problem getting to that site are from different ISP. I guess either it is our ISP problem(but they can access that site) or that site blocks some IP and I am on one of them. I did call the other user (of the same DNS),he had the same problem with me. But he can use in some other locations inside the whole LAN but different DNS. Even when he tried to put different DNS, he couldn't get to that site. Isn't it weird? My final guess is that bbs.mit.edu (the site) blocks some IP.

Strauss III; [EMAIL PROTECTED] Subject: RE: help with network problem Hello. Are you running any type of dns server? At our company, a website a user goes to changed it's ip. Our provider could go there, but from our site we could not. I went to our dns server, found several records missing. I deleted the website out of the dns server, went to it, saw it rebuilt the site info in dns. When you access the site from other locations, are you going through a different isp? If so, then it may point to a dns server. Have you tried getting other users on the isp to access the site?

I asked my ISP about the possible block, they denied it and they can access to that site, so I guess it may not be the problem. I don't know whether that bbs site will block me, which I see no reason, but I would try to see whether that is the problem. Do you know any software that can help you to detect whether some website block your IP? Irene -----Original Message----- From: Burton M.

The usual "it's not there, silly" message is Could not open a connection to host: Connect failed... Connection lost would seem to indicate that the tcp/ip connection was established and then dropped. It's a "bbs" type site. Perhaps your ISP is blacklisted by the site? That is they have chosen to block connections from you or part of your ISP's range or your whole ISP or somebody upstream of them... I think you need to ask the BBS if they are doing any blocking... -----Burton
