We are getting Event ID 2013 and 2012 errors on our Microsoft 2003 Enterprise Server that is saying SMTP could not connect to the DNS server and the Exchange server is a DNS server and also SMTP could not connect to any DNS server. Either none are configured or all are down. E-mail flow appears to be unaffected but this error is troublesome. We have two DNS servers. Pinging each other does not produce an error. Running DCDIAG /TEST:DNS /v produced a FAIL message on FORW and it said our domain has failed? Any assistance offered would be greatly appreciated.
