'  IWAM account synchronization utility
'
'''''''''''''''''''''''''''''''''''''''''''''

'  Description:
'  ------------
'  This admin script allows you to update the launching identity of
'  all IIS COM+ application packages that run out of process.
'
'  There are certain operations that may cause the IWAM account, which
'  is the identity under which out of process IIS applications run, to
'  become out of sync between the COM+ data store and IIS or the SAM.
'  On IIS startup the account information stored in the IIS Metabase
'  is synchronized with the local SAM, but the COM+ applications will
'  not automatically be updated. The result of this is that requests
'  to out of process applications will fail. 
'
'  When this happens, the following events are written to the system 
'  event log:
'
'  Event ID: 10004 Source: DCOM
'  DCOM got error "Logon failure: unknown user name or bad password. " 
'  and was unable to logon .\IWAM_MYSERVER in order to run the server:
'  {1FD7A201-0823-479C-9A4B-2C6128585168} 
'
'  Event ID: 36 Source: W3SVC
'  The server failed to load application '/LM/W3SVC/1/Root/op'.  
'  The error was 'The server process could not be started because 
'  the configured identity is incorrect.  Check the username and password.
'
'  Running this utility will update the COM+ applications with the
'  correct identity.
'  
'  To Run:  
'  -------
'  This is the format for this script:
'  
'      cscript synciwam.vbs [-v|-h]
'           -v verbose: print a trace of the scripts activity
'           -h help: print script usage
'  
'  NOTE:  If you want to execute this script directly from Windows, use 
'  'wscript' instead of 'cscript'.
