Event Type:	Warning
Event Source:	DNS
Event Category:	None
Event ID:	9999
Date:		3/29/2001
Time:		5:20:12 PM
User:		N/A
Computer:	DNS
Description:
The DNS server has encountered numerous run-time events.  These are usually
caused by the reception of bad or unexpected packets, or from problems with
or excessive replication traffic.  The data is the number of suppressed
events encountered in the last 15 minute interval. 
Data:
0000: 14 00 00 00               ....    




Event Type:	Warning
Event Source:	DNS
Event Category:	None
Event ID:	7062
Date:		3/29/2001
Time:		5:20:12 PM
User:		N/A
Computer:	DNS
Description:
The DNS server encountered a packet addressed to itself -- IP address
216.184.208.169. 
 
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 servers 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 this DNS
server unless subzone is also on this server. 
 
Example of self-delegation: 
  -> This DNS server dns1.foo.com is the primary for the zone foo.com. 
  -> The foo.com zone contains a delegation of bar.foo.com to dns1.foo.com, 
  (bar.foo.com NS dns1.foo.com) 
  -> BUT the bar.foo.com zone is NOT on this server. 
 
Note, you should make this delegation check (with nslookup or 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. 
Data:
0000: 50 25 00 00               P%..
