Cannot send email - DNS error
|
|
|
| Hi, I keep getting the following error message in the event log:
SMTP could not connect to any DNS server. Either none are configured, or all
are down.
I have an exhange 2003 server that uses this SMTP as a smart host. Problem
is email is getting stuck in the queue and not going anywhere. I have the
server configured with both our internal DNS servers which seem to work
fine - we can resolve all internet domain names, pinging them from the SMTP
server works fine!
Ive dont the Nslookup on the SMTP server and it bring up the internal name
servers. Other than that I dont know how to fully use it to troubleshoot
this DNS problem
Id really appreciate any help with this!
Thanks,
Grant

| Grant -
You would probably be better served posting this question in the DNS
newsgroup. Also, some people take a dim view of cross-posting. Try one
group, if they can't answer it, try another.
Cheers,
John
