I have an Email server (Win 2K8 & Exchange 2007 SP1) that is unable to connect to another email server on port 25. I have tested the connection via telnet from both my desktop and the email server. My desktop connects just fine but the email server fails. The email server is the (Active Directory) DNS server for both my desktop and email server itself.
NSLOOKUP works on both machines:
I have tried: 'ipconfig /flushdns' and clearing the cache from the DNS server but neither worked.
Any held would be appreciated.
