If you cannot ping by IP, you can rule out DNS at this point. You will want to concentrate on routing (are they in the same subnet?) and firewalls blocking traffic. If you are using DHCP, verify the new client is receiving the same IP and DNS information as the rest of the clients. Run ipconfig /all from a CMD window on a functional and non-functional computer and compare the two, better yet, post it here. ...D ----- Original Message ----- From: Joel Parker <jparker@xxxxxxxxxxxxxxx> Date: Mon, 20 Sep 2004 14:10:46 -0500 Subject: [exchangelist] Outlook question To: "[ExchangeList]" <exchangelist@xxxxxxxxxxxxx> http://www.MSExchange.org/ When I setup a new Outlook client they are unable to connect to the external Pop3 mail server. I get the message that outlook could not find server. However, all of my existing outlook clients are working. This only happens on new computers as I bring them online. I am able to surf to the web interface of this mail server with no problems. I am not able to ping from the new setup either by ip or name. I thought it might be DNS problem but why do the others work? I thought is might be ISA problem but again why do the pre-existing work? Any suggestions on where to start looking for problem?
