Just had a scary moment when a production MVC application went down due to MS Updates removing the MVC 3.0.0.0 dll and replacing it with MVC 3.0.0.1.
Although we located the MS Hotfix (MS14-059), the installer gave us a worrying "Installer Ended Prematurely" error.
The solution was simple - the server needed a reboot to allow it to install some pending updates before the Hotfix could be run.

VBScript / Classic ASP value equivalency crib sheet
DBNULL VALUE
Equivalent to: NULL
ZERO VALUE
Equivalent to: FALSE
STRING NUMBER VALUE (e.g "0")
Equivalent to: NUMBER VALUE (but STRING ZERO is not FALSE!)
EMPTY VALUE / UNDEFINED VALUE / UNPROVIDED REQUEST VALUE
Equivalent to: FALSE (but not NULL!)
EMPTY STRING ("")
Not equivalent to FALSE, EMPTY, ZERO or NULL!
NOTE: If you compare NULL with anything, it just returns NULL, not TRUE/FALSE
NOTE: While 0 is equivalent to FALSE, 1 is NOT equivalent to TRUE
