You can use the following registry subkey to modify the update interval: HKEY_LOCAL_MACHINE\SYSTEM\Current Control Set\Services\Tcpip\Parameters\Default Registration Refresh Interval Data type: REG_DWORD Range: 0x0 – 0x FFFFFFFF seconds Default value: 0x15180 (86,400 seconds = 24 hours) for Windows 2000 Professional Default value: 0x E10 (3,600 seconds = 1 hour) for Windows 2000 Server and Windows Advanced Server Scope: Affects all adaptors This specifies the time interval between DNS update registration updates.
The default Time To Live (TTL) value used for dynamic registrations is 20 minutes.
=============================================================== When a client shuts down, and later returns past the lease time, it may get a different IP address.
With the default settings, a duplicate A record gets registered by DHCP with the client’s new IP.
By default, the ACL gives Create permission to all members of the Authenticated User group, the group of all authenticated computers and users in an Active Directory forest.
This means that any authenticated user or computer can create a new object in the zone.
A quick Facebook read the first line and click “Like,” seems to be the norm. And yea, I had to state Windows 2000 and newer, because this stuff doesn’t apply to older Windows versions.
Well, I will also offer the nitty gritty below the summary for those who want to read. But DHCP will register its PTR (reverse entry) record.
This is because the client will not update itself due to the current record in DNS is beyond the lease period.
This happens even though DHCP registered the record.
.================================================================= There are some misconceptions prompting fears that Scavenging will remove everything in your zone, includind servers.
Please understand, the main thing that scavenging works on is the timestamp.
You can use the following registry subkey to modify the TTL value: HKEY_LOCAL_MACHINE\SYSTEM\Current Control Set\Services\Tcpip\Parameters\Default Registration TTL . Scavenging Refresh and No Refresh settings must be equal to or less than the lease period.
