Every week I get a call from the Help Desk asking me to look at a server which they can no longer PING. I find that I cannot access the server via DNS but IP is OK and find that if I issue an “IPCONFIG /REGISTERDNS” on the server, DNS “kicks-in” and all is good again.
I checked the DNS server and the record looks like this:
IP Address: 10.0.0.55
Update associated pointer record (PTR): Checked
Delete this record when it becomes stale: UnChecked
TTL: 0:0:20:0 (DDDDD:HH:MM:SS)
Happens randomly to about one server a week, never the same one.
Can anyone suggest why this would be happening?
Domain Controllers are Win2K8 R2. Servers are mostly Win2K3 SP2.
