I have monitored some problems with the IP configuration during job execution. It looks like the DNS server name and the domain suffix is changed sometimes.
I would like to find corresponding events in the event log. For this purpose I want to know: How can I identify the point of time when the IP configuration change occurred?
Edit: The question has been marked as duplicated. The referred question handle the IP history of the PC. But none of these other questions (and answer) touch the important detail:
What DNS server address has been assigned at what time?
Therefore I voted to reopen my question.
Anyway, I followed the tips to extend the logging with event log. No events of DHCP result changes have been logged, although the DNS lookup changed after some days.
Edit: I did not found an answer to question. But the reason for the DNS change was an additional router that should provide access to a WLAN. Accidentally the DHCP server of that router was enabled and gave the wrong DNS server address.
