'Script to check the status of a DOMAIN controller and report to Nagios
'requires DCDIAG.EXE
'Author: Felipe Ferreira
'Version: 3.0
'
'Mauled over by John Jore, j-o-h-n-a-t-j-o-r-e-d-o-t-n-o 16/11/2010 to work on W2K8, x32
'as well as remove some, eh... un-needed lines of code, general optimization as well as adding command parameter support
'This is where i found the original script, http://felipeferreira.net/?p=315&cpage=1#comments
'Tested by JJ on W2K8 SP2, x86
' W2K3 R2 SP2, x64
'Version 3.0-JJ-V0.2
'Todo: Proper error handling
' Add /help parameter
' Add support for the two tests which require additional input (dcpromo is one such test)
'Version 3.0-JJ-V0.3
' Removed some surplus language detection code
' Including non-working English test on a W2K8 x32 DC
' Added support for multi-partition checks like 'crossrefvalidation'. Previously the last status result would mask previous failures
' Incorporated Jonathan Vogt's german and multiline tests
