刚刚正在群里聊得起劲呢，朋友Q我说，近几天他有一台web服务器访问不是很快，而且一天当机一次，服务器系统资源占用消耗也并不是很大。当机时出现页面几乎打不开的情况。根据pathping 和tracert统计值每一个hop都不大，不存在time out的情况。重起IIS后，速度恢复，但过半天又当了。 因为这台服务器安全一直是我在负责，呵呵，应该不大可能出现被入侵的情况。于是上服务器： 呵呵，找到答案了，是性能记数据器在作怪，呵呵。再Search一下发现： SYMPTOMSAfter you install Windows 2000 on a drive that uses the FAT or FAT32 file system (that was formatted during the installation process) and install Internet Information Services (IIS) in the same Setup process, event ID 2003 warning messages may appear in the Application event log when you start System Monitor and add counters. This issue does not occur with NTFS drives that do not have a service pack, if the FAT or FAT32 drive is formatted before you run Windows 2000 Setup, or if you add IIS later. The event ID 2003 warning message has the following text: The configuration information of the performance library "C:\\WINNT\\system32\\infoctrs.dll" for the "InetInfo" service does not match the trusted performance library information stored in the registry. The functions in this library will not be treated as trusted. The configuration information of the performance library "C:\\WINNT\\system32\\aspperf.dll" for the "ASP" service does not match the trusted performance library information stored in the registry. The functions in this library will not be treated as trusted. RESOLUTIONTo resolve this problem, run the following commands at a command prompt in the %SystemRoot%\\System32 folder to unload and reload the IIS performance dynamic-link libraries (DLLs). After you run these commands, the warning messages are not logged: unlodctr w3svc
