This is just a small heads-up post for all the VCDX candidates.
Almost every VCDX application I read mentions the fact that they needed to increase the Disk TimeOutValue (HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Disk) by to 60 seconds on Windows machines.
The truth is that the VMware Tools installation (ESX version 3.0.2 and up) will change this registry value automatically. You might want to check your operational procedures documentation and update this!

VCDX tip: VMtools increases TimeOutValue
15 sec read
for 2000 and 2003…
Since vista, windows 2008, windows 7 and windows 2008r2 the TimeOutValue is always at 3c = 60
for NFS storage, the best practice is to set this value to 125. p270 scott lowe
