Zorluk: KolayWindows Client Networking Configuration

A Windows 11 workstation is unable to reach an internal web server using its hostname following a server IP address migration, even though the corporate DNS record has already been updated. Other workstations can access the site successfully. The technician needs to clear the cached DNS entries on the local client using the command prompt. Which command should the technician run?

  1. ipconfig /flushdnsCevap
  2. B
    ipconfig /registerdns
  3. C
    nslookup /flush
  4. D
    netsh interface ipv4 reset

Cevap

The command 'ipconfig /flushdns' should be executed to clear the local DNS resolver cache.
The command 'ipconfig /flushdns' explicitly clears the local DNS resolver cache, resolving hostname lookup errors caused by outdated cached IP addresses.

Adım Adım Çözüm

1
Identify the issue context
The client system is retaining stale DNS address records in its local cache while the central server records have already been updated.
Windows caches previous host-to-IP mappings locally to speed up name resolution.
2
Select the appropriate CLI utility and switch for clearing cached DNS entries
Executing 'ipconfig /flushdns' flushes and resets the contents of the DNS client resolver cache.
Flushing the cache forces the local Windows system to issue a fresh query to the primary DNS server upon the next domain name lookup request.
