 +On your Windows Server hosts, change the disk I/O timeout value to 60 in the Windows registry, as follows:
 +
 +    In Windows, click Start > Run.
 +    In the dialog text box, type regedit and click Enter.
 +    In the registry browsing tool, locate the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Disk\TimeOutValue key.
