I am getting this error message in event viewer on a server running Server 2000. The interval between errors is about 15 minutes. This server is a DC and is running Exchange Server 2000.
Event ID 5504
The Dns server encountered an invalid domain name in a packet from 192.168.24.1. The packet is rejected.
The IP listed is the router. If I restart the DNS server service, the error ceases for a few days and then starts again. Also, Incoming mail isn't being delivered while the error is occurring. DNS Server is setup as a forwarder.
Can anyone provide me any information on how to correct this issue?
