My Proxy software requires me to enable DNS in the TCP/IP setting of each client on the network. The IP of the dialing computer must be entered into the DNS search order list. However, when I do this Outlook takes A long time to connect to the Exchange server, and keeps timing out. It seems like the TCP/IP can't cope with both. Or maybe the client machines are having trouble locating the Exchange server because of enabling the DNS. Can any Exchange experts help me. I would greatly apreciate it. Kind Regards, Andy_
