dns server is not used after some time
I have a set of host names that could be resolved only with a specific remote dns server A, so I have several DNS servers in network card TCP protocol settings.
This works for some time. I do not know exactly, but that could be hours or even days. After that time host names from DNS just stop resolving. I can not open them in web browser, ping etc. However nslookup can resolve these host names.
I solve this problem by "updating" dns server configuration. I just change order of DNS servers, I do not think that order plays any role but it just resets internal state of windows DNS system.
Sometimes connection to DNS server A is lost, so I suspect it is a cause for such behaviour, i.e. DNS server is not accessible then it is not queried any more.
How can this issue be solved?
