(No output returned from plugin)

[Anthony Montibello]

Most plugins (including NSCA,NRPE, NSClient++, NC_Net ) that allow input
form scripts require output from Standard Out.
to do this with a VB script, the script must be done via CSCript.exe
otherwise the script opens an pop up for the output.  (I can see from above
you did call CScript)

Have you tested the script via a command window to validate the output is
going to the command window?  I thought CScript uses the //B to redirect
output to console? (I do not use VB Scripts frequently)
