| Description | DNS Server encountered a packet addresses to itself -- IP address w.x.y.z. The DNS server should never be sending a packet to itself. This situation usually indicates a configuration error. Check the following areas for possible self-send configuration errors: 1) Forwarders list (DNS server should not forward to themselves). 2) Master lists of secondary zones. 3) Notify lists of primary zones. 4) Delegations of subzones. Must not contain NS record for DNS server Example: -> This DNS server dns1.microsoft.com is the primary for the zone microsoft.com. -> You have delegated the zone bar.microsoft.com to bardns.bar.microsoft.com and are NOT running the bar.microsoft.com zone on this DNS (dns1.microsoft.com). Note, you should make this check (with nslookup of DNS manager) both on this DNS server and on the server(s) you delegated the subzone to. It is possible that the delegation was done correctly, but that the primary DNS for the subzone, has any incorrect NS record pointing back at this server. If this incorrect NS record is cached at this server, then the self-send could result. If found, the subzone DNS server admin should remove the offending NS record. |
| Event Information | After you apply Service Pack 4, the DNS server begins logging Event 7062 CAUSE : This error is caused by a configuration error or is the result of a delegation of a domain (or subdomain) to a server for which there is no zone file (lame delegation). RESOLUTION : To resolve this issue, check for the following conditions: Forwarders DNS can be configured to forward off-site queries to designated servers. Be sure that the DNS server is not configured to forward these off-site queries to itself: Select the server, click DNS, and then click Properties from the menu. Click the Forwarders tab. If the servers own IP address is listed, select it and click Remove. After you make this change, make sure to stop and restart the DNS service. Master List of Secondary Zones A secondary zone is configured with a list of the master or primary server(s). Be sure that the servers own IP address is not listed as one of the IP master(s): Select the secondary zone, click DNS, and then click Properties from the menu. Click the General tab. If the servers own IP address is listed in the IP Master(s) section, select it and click Remove. Notify Lists Microsoft Windows NT DNS Server allows the Administrator to specify (on the primary DNS server) any secondary DNS servers that should be notified immediately of changes to the Zone file. Be sure that the DNS server is not configured to notify itself: Select the primary zone, click DNS, and then click Properties from the menu. Click the Notify tab. If the servers own IP address is listed, select it and click Remove. |
