Hi Tom,

That's not entirely true, Tom; everyone I build out gets split DNS, too.

Hi Mark,

Make sure that you have force basic authentication, and that all
machines have the correct CA cert in their Trusted Root Certificate
Authorities.

Also, make sure you have configured the correct entry in your HOSTS file
to support the redirect (unless you've created a proper split DNS, but
no one does that expect me and Jim :-)

HTH,
Tom

No blocked connection from the filters, and the fws log only shows my
rdp connections. On my side, there are no log entries either, just the
occasional ping being blocked. And, of course, 443 allowed.

The inbound listener is configured for all IP addresses (dial-up) and to
accept basic auth only. I had to configure a packet filter for inbound
443 access however to make this "work" actually. Without the filter, I'd
be getting host not found errors or just a blank page. 

Thanks
Mark
