Ok, I bought a new server installed Win 2003 and Exchange 2003. The migration of the mailboxes went great until it was time to stop the SMTP service on the old Exchange server. If I stop it nothing happens to the mail no in or outbound. If I turn it back on, some things go through(out) but nothing comes in. I have checked my DNS server and have no clue what to look for.
Currently my mail exchanger is set the dldc which is the new Exchange server. The old server will remain my DNS server. What am I missing? I thought it might have something to do with the ISA box but now I am leaning more torwards DNS. Anyone have any clue what I need to look for on the old or new server? If you need more infor please let me know.
