We have just setup a new exchange 2003 server in a new domain. There is an existing exchange server working within the same IP scheme but it is running on windows 2000 server and there is no room on the disk. The new server cannot send or receive even though we have an MX record from our ISP that manages our domain. We also couldn't do ADPrep from one domain to another. I hope someone out there can help us. The new exchange server is set up just like the old one but it won't route. HELP!!!
