The WIN2003 server reported an error with the following error message: An I/O operation initiated by the Registry failed unrecoverably. The Registry could not read in, or write out, or flush, one of the files that contain the system’s image of the Registry. Registry failure caused by an I/O operation. The registry, which contains the system image of the registry, will not be able to read, write, or refresh. In cases like this, it is generally necessary to restart the system with and restore the system configuration information with an emergency repair disk. However, there is no remote desktop to connect and restart (plus the console parameter is also not available). There is also no restart with serverView hardware monitoring software, so you can’t go to the IDC room of century Internet. The shutdown – I command suddenly occurred to me. Ping first, it looks normal, then add the REMOTE host’S IP using shutdown – I, and reboot successfully.
