I am expierencing problems with internal DNS name resolution. The problem seems to be the internal active directory domain name is set to xyz.com. The same domain name, xyz.com is also available externally for website hosting. Client workstations are configured use the DNS server on the active directory domain controller. Randomly, the client workstation will attempt to resolve names using external DNS name servers.
I would like to prevent DNS name resolution for internal resources from using external DNS servers. At the same time still allow internal clients to resolve xyz.com website access.
A netgear router/firewall has been installed as well. Any suggestions for a remedy?
