| Event Information |
7050 event are caused by high load situations, and are generally
exacerbated if you have debug logging enabled on the DNS server. Under high
load with debug logging enabled the DNS server is not capable of writing the
log and answering queries. Turning off debug logging should make these go
away. Following information from newsgroup post may help you to understand more about this Event: 1.This happened exactly once so far on our internal Win 2k3 DNS servers at exactly the same time. After investigating the problem, it seems that an IT person who was running a port probe across the entire subnet caused it. 2.You may have a firewall with a too-aggressive TCP timeout, or somebody may be port scanning you, or there could be an errant workstation on the LAN issuing corrupt packets, or misconfigured ISA server. Anyway, it will be something along those lines. If you cant narrow it down, and nobody else knows of a specific cause for this on this forum, crank up a sniffer (Ethereal or Netmon for example), and capture the stuff to decipher what is going on. |
