Question

DNS Server Is Not Responding to Few PCs Everyday

By RGS23 ·
Hi, I'm new here!

I wanna ask something about DNS-related issue.

So my daily scenario goes like this:

I go to work, and some PCs (~5-10) are always having issues with their DNS. They always have no internet connection. I fix it every morning by switching from static to DHCP and vice versa. Sometimes it takes a lot of time, sometimes it goes less than 1 minute. But eventually, it will be fixed. I'm really confused and frustrated as I can't seem to understand the problem and a permanent solution. I tried googling the fixes but every post gives the same solution.

Solutions I always do:

Switch Static IP to DHCP and vice versa
Changing the DNS Server Address to 8.8.8.8, 8.8.4.4, and if it doesn't work, I put our default gateway's address.
Running CMD on admin, typing 'netsh int ip reset', 'netsh winsock reset', 'ipconfig /flushdns'
And of course, restarting the PC itself.

Seeking for help, thank you!

You shouldn't need to do that, but I need more info to recommend a solution. What are you using for dns? Can you ping your dns server? can you ping your default gateway? If you are using static IPs I'm guessing you probably have duplicate IP addresses on your network. They should all be dhcp, and if you have to use static for some reason those addresses should be reserved or excluded from dhcp so someone else doens;t use them
