Avoid Delayed Write Failed in Windows 2k/2k3 on ESX

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.
