MSSQLm.nse actually tries to login to the SQL server using 'sa' and a
blank password.  That *part* of the script is intrusive.  The rest of
it is discovery and is very useful for version detection.  Break it in
to two scripts maybe?

HTTP_open_proxy.nse could probably be just discovery.  It sends a
single request that is a normal looking, non-malformed request.

I don't know enough about DNS to read through zoneTrans.  Since zone
transfers are a popular recon technique, if that is actually what the
script does, perform a full zone transfer, it is definitely intrusive.
 It it just determines whether or not a zone transfer is possible but
doesn't actually do it, it would be discovery.

These are just my opinions and I'd be eager to hear what others think.
