Hi. A few days back, I registered my PC’s own host resource record at a website in a network. Ever since, I have been observing performance degradation. What could be the possible reason behind it? Why is there a need to scavenge stale resource records?
Make Your PC Sage – Scavenge Stale Resource Records!
The issue that you are facing here is due to the presence of stale resource records in zone data. What exactly happens is that when a computer joins a network, records automatically get added to the zones. However, on leaving the network, they are not automatically removed. It is also possible that your PC was not properly disconnected from the network following which records may not have been deleted. Because of this, records keep on getting accumulated and slow down the performance of the computer. To solve this, features such as aging, scavenging and time stamps is present in DNS servers. Time stamps are allotted to the records which are added at run-time according to the date and time of the server. Aging of a record determines the time for which it has been present in a location according to a particular refresh time. Scavenging involves the removal of records which have exceeded this refresh time. So, to solve your problem, you need to scavenge stale resource records at the server.
