I've setup and configured an Exchange 2003 server. Everything is fine on the server side. However, on my client side, on certain clients, when i try to create a profile and connect to a mailbox on the exchange server using outlook, i get a "The name cannot be resolved. The name cannot be matched to a name in the address list" error. On the other clients, i have no problems connecting to the server. I've checked through the client settings. All seems to be in order. I obtain my network settings from DHCP. I can even ping the Exchange server. I've even tried running netdiag to test my connections. There don't seem to be anything wrong with the clients. Please help !!
