When you use the ping command, is the name correctly resolved? If the computer cannot resolve the name of the exchange server it can't connect. If you don't have a Dns in a brach office, you can Use Wins or edit the Hosts File. If You use the exchange server's Ip Address it change automatically to the name of the server and stop working when the name is not resolved... -----Mensagem original----- De: listrahul [mailto:listrahul@xxxxxxxxxxxxx] Enviada em: Thursday, October 31, 2002 2:13 AM Para: [ExchangeList] Assunto: cannot connect to exchange server Hi, I have a wierd problem.This is the background. I havea Windows XP Pro machine with Outlook 2002 running. For some reason I had to run a Windows XP repair from the CD. After which my Outlook stopped connecting to the exchange server for some unknown reason. I tried it for a different user from the same machine. Finally I also changed my machine IP and also the machine name. Still the problem continued. Also tried uninstalling Office 2002 and installing it back ... problem continues. Can somebody help me with this .... please ... Warm Regards, - Rahul
