I am a new admin at a small company with just one server, Win Server 2003R2. This server does everything, DHCP, DNS, File and print, and Exchange.
I notices a number of DNS errors in the event logs: The dynamic registration of the DNS record '_ldap._tcp.h2o-law.com. 600 IN SRV 0 100 389 server.h2o-law.com.' failed on the following DNS server:
DNS server IP address: 18.104.22.168
Returned Response Code (RCODE): 5
Returned Status Code: 9017
Looking at the DNS I was horrified with what I saw - see attched image file.
Given that this server is absolutely mission critical and that there is no other dns server in the business, and it is running IIS and Exchange, I just want confirmation that my thoughts on how to get the DNS into a more sensible config is right.
Only missing piece of information is that nobody seems to know the IP addresses of the ISP DNS servers.
Please tell me how you would change the config of the DNS and TC/IP of the NIC.
