How is external DNS set up? Forwarders? Root hints? I usually use forwarders. See if you can ping the listed forwarders; then try a Nslookup using those IPs as the server. Any firewall rules that might have been inadvertently changed? It sounds like DNS queries aren't getting replies from outside. Does internal DNS work?
You might throw wireshark on the box and see what the DNS queries do... *********************** Charlie Kaiser charl...@golden-eagle.org Kingman, AZ *********************** > -----Original Message----- > From: Art DeKneef [mailto:art.dekn...@cox.net] > Sent: Friday, May 01, 2009 8:16 AM > To: NT System Admin Issues > Subject: Server 2003 DNS issue > > Have a client that is having trouble with Internet > connectivity and Exchange sending mail externally. > > > > Has a SBS 2003 server up to date as of two weeks ago, nothing > changed since then that I know of or can see.
