I have two desktop computers and recently set up a third computer, a Windows Server 2012 box, for which I installed DNS on it and set it up as a domain controller. I was able to successfully set up each computer to be part of the new domain. There is a router, which goes to the outside world.
Issue:
I cannot ping the other computer via a fully qualified DNS domain name. I also set up an A-record, which neither computer can ping.
Domain: myoffice.com
Computers: ComputerA, ComputerB
Fully Qualified Names: ComputerA.myoffice.com and ComputerB.myoffice.com
Each computer can ping itself using the computer name or its fully qualified name. The server, however can ping either computer.
Each computer has the Primary DNS Gateway set to the server's IP address and the Secondary Gateway set to the router's IP address. The router provides all DHCP addresses.
I created a new A record in the DNS Manager in [DNS | | Forward Lookup Zones | myoffice.com] setting mail.myoffice.com to the IP address of the server. Neither workstation can see the new A-record. I even did an "ipconfig /flushdns", not that that helped.
Obviously, I am not doing something that I should do. How do I troubleshoot the problem(s)?
Update:
Each client computer can ping the IP address of the domain control and by its computer name, just not the fully qualified domain name of the server.

DNS settings are incorrect. DNS IP's point to DNS servers, the terminology of "DNS gateways" is incorrect and misleading as DNS servers only respond to queries, they don't do any packet routing.
On Windows Server:
-In IPv4 TCP/IP properties change primary DNS server to 192.168.0.8 (no secondary DNS)
-Do an "ipconfig /registerDNS", reboot.
In DHCP server scope (currently this is the router):
-Change primary DNS server to be 192.168.0.8 (Windows Server IP)
-Do not use a secondary DNS server unless there is a 2nd AD DNS server on the LAN.
Note that w/ a Windows server in place then network browsing works better if DHCP is done on server & DDNS is enabled. See:
http://technet.microsoft.com/en-us/library/cc771255.aspx http://en.wikipedia.org/wiki/Dynamic_DNS#Function
Workstations:
Reboot or "ipconfig /renew" after above changes are completed.
Yes, if the Windows DNS server goes down then the internet is also down. If that's the case then there will be larger issues and the DHCP scope on the router can be enabled at that time.
Because AD depends on DNS internal workstations should only use internal AD DNS servers. Having an external 2ndary DNS will cause unpredictable browsing, logon and network performance issues in an AD domain.
Using a .com like BVOffice.com for an AD name is often problematic and not recommended IMO. Currently there are no public DNS records but if this is not your domain name then I would either buy it, but I would still change the internal AD name to bvoffice.local. Using .com for an AD name can be managed (mostly...) but requires a good understanding of DNS and TCP/IP.
