Well, yes, but unless I've badly misunderstood the situation, all
that's necessary to mitigate this bug is to interpose a non-buggy
recursive resolver between the broken machine and the Internet at
So just make sure your corporate/campus edge router has a reasonable
named on it, and point everything broken at that, and you should be ok,
even though, as you note, DEC won't be updating VMS any time soon. :-)
