Zorluk: OrtaWindows Client Networking Configuration

A Windows 11 client workstation in an enterprise environment can successfully access internet websites by URL and reach local resources using IP addresses. However, when users attempt to connect to internal file servers using domain hostnames (such as \\fileserver.corp.local), the connection fails. A technician runs `ipconfig /all` and observes that the IPv4 network adapter is configured with a static IP of 10.1.5.50, a gateway of 10.1.5.1, and public DNS servers (8.8.8.8 and 8.8.4.4). Which of the following networking updates will resolve the hostname resolution failure while maintaining internet connectivity?

  1. Reconfigure the primary DNS server IP address to point to the internal Active Directory domain controller.Cevap
  2. B
    Add a secondary default gateway address corresponding to the local domain controller's IP address.
  3. C
    Run the command `ipconfig /flushdns` with the switch `/release` to clear invalid gateway routes.
  4. D
    Open Network Connections in Control Panel and enable the Windows Feature switch for Active Directory Name Resolution.

Cevap

Reconfigure the primary DNS server IP address on the network adapter to point to the internal Active Directory domain controller.
Internal active directory domain names can only be resolved by internal DNS servers containing the local zone files. Assigning public DNS servers prevents clients from locating internal network shares by hostname.

Adım Adım Çözüm

1
Analyze the reported connectivity symptoms
The client can reach external sites by URL (public DNS works) and internal resources by IP (IP routing works), but internal name resolution (.corp.local) fails.
Public DNS servers like 8.8.8.8 do not hold zone records for private internal enterprise domains.
2
Identify the required TCP/IP property modification
Change the client adapter's Preferred DNS Server setting from 8.8.8.8 to the internal IP address of the local domain controller/DNS server.
The internal DNS server will resolve internal hostnames directly and forward external name queries to public DNS servers.
