So, the situation is as follows. Our production servers are the most important servers being affected but this is happening randomly. I can not build a pattern for servers that are being affected to ones that arent. It seems to be completely random.
We do reboots once a month on our servers. Every time we reboot, random servers will lose their STATIC a record in DNS. It will propagate almost instantly too. We will then have to either manually enter another A record in DNS or do a ipconfig /registerdns and wait 15 minutes or so.
All of our servers are on a VLAN with no DHCP, and they have statically assigned everything. The option on the NIC to enabled registering of the address in DNS is enabled.
We have scavenging, but its every 7 days (of anything older than 7 days) and the cycle was started on a Monday, and we restart on Thursday. What do you think I should do?
Answer
Did you disable the “DHCP Client” service on these servers?
The DHCP client service is the service that registers the computer in DNS.
Here is the description of the service:
Registers and updates IP addresses and DNS records for this computer. If this service is stopped, this computer will not receive dynamic IP addresses and DNS updates. If this service is disabled, any services that explicitly depend on it will fail to start.
