• ISP ka DNS server down ho gaya ho
• Wrong DNS settings network adapter mein
• Outdated ya corrupt network adapter driver
• DNS Client Service Windows mein band ho gayi ho
• IPv6 conflict create kar raha ho
• Router ka DNS cache corrupt ho gaya ho

Fix 1: DNS Cache Flush Karein

DNS cache mein purani ya corrupt entries hoti hain jo naye DNS requests ko block kar deti hain. Flush karne se ye sab saaf ho jaati hain.

Fix 2: DNS Server Manually Google Ya Cloudflare Par Set Karein

Aapke ISP ka default DNS server slow ya down ho sakta hai. Google (8.8.8.8) ya Cloudflare (1.1.1.1) DNS bahut fast aur reliable hain.

Steps:

1. Win + I dabayein > Network & Internet > Advanced network settings
2. Apna active adapter dhundhen (Wi-Fi ya Ethernet) > Edit par click karein
3. Manual select karein > IPv4 on karein
4. Preferred DNS mein type karein: 8.8.8.8
5. Alternate DNS mein type karein: 8.8.4.4
6. Save karein aur browser refresh karein

Agar aap firewall se related issues bhi face kar rahe hain saath mein, toh humara Windows 11 Firewall Blocking Internet guide padhen — dono problems ek saath ho sakti hain.

Fix 5: DNS Client Service Restart Karein

Windows 11 mein ek “DNS Client” service hoti hai jo DNS requests ko handle karti hai. Agar ye service band ho gayi ya stuck ho gayi, toh DNS error aata hai.

Steps:

1. Win + R dabayein > services.msc type karein > Enter
2. List mein DNS Client dhundhen
3. Us par right-click karein > Restart select karein
4. Agar Restart greyed out hai, toh double-click karein > Startup type: Automatic karein > Start > OK

Outdated ya corrupt driver bhi DNS error ki wajah ban sakta hai. Driver update karne se ye fix ho jaata hai.

Steps:

1. Win + X > Device Manager open karein
2. Network Adapters expand karein
3. Apne Wi-Fi ya Ethernet adapter par right-click karein > Update driver
4. Search automatically for drivers select karein
5. Update install hone ke baad restart karein

Fix 7: IPv6 Temporarily Disable Karein

Windows 11 by default IPv6 use karta hai jo kabhi kabhi DNS conflict create karta hai, specially older routers ke saath.

Steps:

1. Win + R > ncpa.cpl type karein > Enter
2. Apne active adapter par right-click karein > Properties
3. Internet Protocol Version 6 (TCP/IPv6) ka checkmark hata dein
4. OK karein > PC restart karein

Agar aap Wi-Fi related problems face kar rahe hain, jaise network profile baar baar change hona, toh humara Windows 11 Network Profile Keeps Changing fix zaroor padhen.

Fix 8: Router Restart + Hosts File Check Karein

Part A – Router Restart:

1. Router ke back mein power button se band karein
2. 30 second wait karein
3. Wapas on karein aur 2 minute wait karein
4. PC se dobara connect karein

Part B – Hosts File Check:

Kabhi kabhi malware ya koi software hosts file mein galat entries dal deta hai jo DNS ko block karta hai.

1. Notepad ko Admin se open karein
2. File > Open > Path: C:\Windows\System32\drivers\etc\hosts
3. Koi suspicious entry dikh rahi hai (jaise google.com ko kisi IP se block kiya gaya ho) toh use delete karein
4. Save karein (Ctrl+S)

Summary: Kaunsa Fix Kab Use Karein

Conclusion

“DNS Server Not Responding” ek irritating error hai lekin zyaadatar cases mein DNS flush karna ya Google DNS set karna se hi fix ho jaata hai. Agar kaam na aaye toh TCP/IP reset aur driver update zaroor try karein.

Agar aapka issue dobara aata hai, toh ISP se contact karein — unka DNS server repeatedly down hota ho toh ISP ko change karne ke baare mein sochna chahiye. Aap Windows 11 Network Sharing issues ke liye bhi hamaari guide check kar sakte hain agar zyada problems aa rahi hain network ke saath.
