Troubleshooting Name Resolution on Client Computers

Clients rely on DNS to resolve hostnames like server01.company.local into IP addresses. Common symptoms of failure include inability to access internal resources, login delays, or failed nslookup results.

🛠️ Steps to Troubleshoot

• ✅ Check DNS Settings:

ipconfig /all

• Confirm client is using the correct internal DNS server.

• ✅ Test Resolution:

nslookup server01
ping server01

• If nslookup fails but ping by IP works, DNS is likely misconfigured.

• ✅ Flush and Renew:

ipconfig /flushdns
ipconfig /release
ipconfig /renew
ipconfig /registerdns

• ✅ Check for Static Config Errors:
  Ensure there are no manually entered wrong DNS servers in IPv4 properties.

• ✅ Use dcdiag /test:dns:
  On domain controllers to check DNS service health.
