We are running Exchange 2003 on a Windows 2003 server in the office. Everything has worked fine for the past 5 years until we switched ISPs. We replaced an XO T1 with a T1 from Broadview ATX. Incoming email works fine but no outgoing email is going out. On the Exhcange server the following event log keeps coming in...
EVENT ID: 2012
SMTP could not connect to the DNS server '184.108.40.206'. The protocol used was 'UDP'. It may be down or inaccessible.
the 220.127.116.11 is the old XO DNS? The network card on the server does not show that IP? Why is that 18.104.22.168 IP still showing up? Where can I check and remove this?
