公司有兩台域控，PDC和BDC(2003 R2 SERVER)，各自都有主DNS（AD集成的），昨天突然PDC宕機，BDC沒有起作用，，重啟PDC後，BDC出現異常。
用Dcdiag命令檢查，PDC沒有問題，正常；BDC發現錯誤，如下：
同時還有一奇怪現像是：在AD1上用\\AD2能訪問，但netlogon和sysvol不能打開，用\\192.168.0.2 (AD2的IP)不能訪問，用PING AD2\PING 192.168.0.2都通；而在AD2本機，用\\AD2和\\192.168.0.2都不能訪問；PING也都通。
為什麼？？？？為什麼？？？？
下麵是BDC上運行Dcdiag的報告：請幫忙分析
