%2 上的主要 DNS 伺服器對區域 %1 的 IXFR (增量區域轉送) 要求傳回不正確的 (格式錯誤) 回應。如果將 %2 上的 DNS 伺服器升級成執行方式是 Windows 2000 或更新版的 Microsoft DNS伺服器、或 IXFR 相容的 DNS 伺服器之後，DNS 伺服器效能及網路頻寬都會增強。

The master DNS server at %2 responded to IXFR (Incremental Zone Transfer) request for zone %1 with an invalid (FORMAT ERROR) response. DNS server performance and network bandwidth will both be improved by upgrading the DNS server at %2 to a run as either a Windows 2000 or later Microsoft DNS server or another IXFR-compatible DNS server implementation.
