I work in a secure environment where our Security dept requires that the DHCP
Client Service be disabled on production servers. The servers have static IPs.

I have observed the following behavior:

1) A server is built the DHCP Client Service is not yet disabled. Server is
IP'd and added to domain. A DNS record is auto-created for the server.
2) DHCP Client Service is later disabled
3) DNS record for the server soon (within 30 minutes or so...maybe
sooner)disappears and/or is automatically removed from DNS.
4) Scavenging is at the default setting of not enabled.

Is this known behavior in that the A record for the server is removed from
DNS when the DHCP client service is disabled on the machine?

Thanks
