Failover in Windows 2000 and Windows Server 2003 Guest Operating Systems
For the Windows 2000 and Windows Server 2003 guest operating systems, you may
want to increase the standard disk TimeOutValue so that Windows will not be
extensively disrupted during failover.
1. Select Start > Run, type regedit.exe, and click OK.
2. In the left panel hierarchy view, double-click HKEY_LOCAL_MACHINE, System,
CurrentControlSet, Services, then Disk.
3. Select the TimeOutValue and set the Data value to x03c (hexadecimal) or
60 (decimal). By making this change, Windows waits at least 60 seconds, for
delayed disk operations to complete, before generating errors.
4. Click OK and exit the Registry Editor program.
