Wired DNS request failure issue
From last week, I began to have strange DNS request issue. I have a home DNS server setup to resolve the names of my home PCs. I have 3 windows 10 PCs and 2 synology NASes. One week ago, every thing is fine. But from last week, my windows PCs will lose DNS resolving function after running several hours. This won't happen at the same time for the 3 PCs. If one windows 10 PC has this problem, the others two may be still OK and all the phones and pads are still good. For the PC having problem, you still can ping the DNS server, but just cannot resolve hostname. I tried the following methods:
- Disable and enable the network adapter won't make it work.
- "ipconfig /flushdns" won't make it work and "ipconfig /displaydns" shows nothing before I flush it.
- nslookup just timeout, I tried set the timeout to 10 and even 100. It seems the PC cannot send out the DNS request.
However a simple reboot of the problem PC will make the PC work again. But you don't want to reboot your PC from time to time.
I searched the web and read some posts but didn't find any clue. I don't think it's server issue. It should be the window 10 PCs. Currently, I don't want to reinstall the system. I have kaspersky installed on the 3 PCs and I don't think it's because of virus or hackers. But I'm doubting whether it's because of Kaspersky itself because one weeks ago I also began to have the "self-signed certificate" issue, which is a bug of current version of Kaspersky.

Hope I can get some answer here. Thanks.
