Hi Ben-- It was just that sort of "link-paste" response that got this whole
thread started. The OP could not substantiate his statements technically,
so the responses become concatenated links to other non-substantiated
claims.

The important thing for readers to walk away with is that Micorosft is *not*
"dropping support for NTLMv2" as the OP claimed. Unfortunatedly, Howard's
quote of "banning MD5 in future code" was stretched by the OP into
"Microsoft drops support for NTLMv2." I wasn't so interested in trying to
correct the OP, as responses showed he couldn't tell the difference between
netlogon protocols and IPSec, but rather, I was trying to make sure that
other readers got better information.

While other protocols and components will continue to be developed, NTLMv2
will be supported for quite a some time. That's really one of the cool
things about Vista- they are making higher level protocols more modular,
allowing customers to plug-in lower-level components to better suit their
needs.

Thanks.
