Event ID: 7053 Source: DNS

DNS Server sendto() function failed. The data is the error.
In our case, we had Windows Server 2003 installed. Installing Windows Server 2003 SP2 resolved this for us. I suspect reinstalling SP1 would have also done so.
See ME884891 for a hotfix applicable to Microsoft Windows 2000.

ME249868 also provides information on this problem.
As per Microsoft: "This problem occurs because DNS encounters a referral to an invalid address for a name server. The referral resource record lists the IP address of the name server as DNS cannot send a query to an invalid address and logs the error against the sendto function."
Note: a supported fix is now available from Microsoft - see ME244132.
For Microsoft Windows NT 4.0 Server the error can occur if the Domain Name Service (DNS) cache file (Cache.dns) is corrupted. See ME317022 link below.
