We have been having random issues with users getting stuck whilst logging on and my gut feeling is that it is a DNS issue. (After powering off/on their PC, logging in as local admin and doing an ipconfig /release /renew they can log on as normal).
I was looking at our DNS scavenging settings and noticed that it seems to be configured a bit differently to how I normally see it configured in instruction guides etc:
Our scavenging/ageing settings for 'all zones' is configured as below:
I am a bit concerned that no-refresh interval is set as 5 days and refresh interval is set as 4 days. I wonder if the problem is occurring on the cross over 1 day of these two periods?
Normally when I see this configured in instruction guides, they seem to both be set as 7 days.
Could this be causing an issue?
