The DNS server encountered a packet addressed to itself - Event ID 7062

Q1: Hello I’m new to this forum and i have a problem, perhaps someone can help me out.  I’m a network admin of a small network and one SBS2003 server.  It has  been running for a bout a month problem free.  Now I am getting DNS errors by the hundreds.  I’m unsure how to fix this problem.   Here is the error message. The DNS server encountered a packet addressed to itself on IP address xxx.xxx.  xxx.xxx The packet is for the DNS name "yahoo.com.". The packet will be discarded. This condition usually indicates a configuration error.

The second issue i think is related.  once a day every day a specific website that is our erp (so its used by 10 people at at time)  times out on all users and is inaccessible from the network.  The server can still connect but the
clients cannot. they can ping it but no connection. are the two related, i
don’t know.  please help.....

A1: I wish you posted the event ID #. Is it Event ID 7062? Is the SBS multihomed computer? How do you setup DNS Forwarders? Or posting the result of ipconfig /all.
