Problem : The DNS Server encountered an invalid domain name. Event ID 5504
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?
Solution: The DNS Server encountered an invalid domain name. Event ID 5504
Seems like we’re getting somewhere; your DNS settings are incorrect; I’m not sure if this causes your 5504 error, but it needs to be fixed.
Assuming DNS is running on your DC: Your DC needs to point to itself *only* for DNS resolution. The clients need to point to your DC as well *only* for DNS. The forwarders section in your DNS is the *only* place in your entire domain where your ISP’s DNS should be listed. If you have a second DC running DNS, let it point to your first DC as primary DNS, to itself as secondary.
In your DNS settings, make sure Dynamic Updates are enabled. Verify that you have a host name entry for your DC, and that the SRV records were created.
