I then created a hosts file for the laptop mapping the internal machines to
their internal addressing - now everything works perfectly.
Get rid of the Host file. That is want WINS is for. Run "IPConfig /All" on the
Client to make sure it is getting all the details correct (ignore the Default
Gateway for now). Make sure the ISA has the correct Access Rule (From=VPN
Clients, To=Internal) so that the client can actually query the internal DNS and
WINS.like it is supposed to. Watch the Live Log (filter set to Source
Network=VPN Clients) to clean up anything else the Client needs that is being
denied.
So it seems that when I connect to ISA using a VPN, ISA is still telling the
connection to use the ISA DNS entries which are all the valid 'external'
addresses - even though I've forced ISA to use the internal DNS servers in
the VPN configuration and forced the VPN client to use the internal DNS
entries.
There isn't supposed to be an "ISA DNS". Get DNS off the ISA. The ISA should
use the Internal DNS just like everything else. The Internal DNS should use the
ISP's DNS as a forwarder and should have it listed in the Forwarders List. The
ISA should have an anonymous outbound access rule for DNS to allow the Internal
DNS to make outbound DNS queries. The Rule should limit it only to the Internal
DNS to eliminate and expose any machines with rouge DNS entries.
