Based on the timestamps (as you can see below, it indicates: Time Generated:
12/15/2005 08:47:08), the errors happened this morning at 847, correct? or
am I misreading what time generated means? I've searched the system,
application and dns event logs, and haven't found any errors with this error
number, or anything at that time at all.
The only error in the dns event log was 4 days ago, event ID 4015:
DNS_EVENT_DS_INTERFACE_ERROR. It only happened once, in the entire log.
