Is DNS scavenging enabled? Are dynamic DNS updates working?

[3s-gtech]

Yup, we had it when I found that DNS scavenging hadn't been turned on. Check your DNS settings - this may also be causing some other oddness around the place too!

[scholes99]

thank you very much to both of you for your help with this

Once you have done the above use nslookup util to confirm that the hostname / computer name is resolving to the ip address that it should be and not someone elses computer.

Scavenge stale resource records is ticked,

no-refresh interval is 1-day

refresh interval is 1 hour

enable automatic scavenging of stale records is ticked and 1 day

Does this happen on all machines or just yours? Could be an "ipconfig /flushdns" resolves your issue as the stale record is cached on your machine.

 

If not, maybe a static record is in DNS that is causing your problems? "nslookup" is your friend.
