    Configure IIS DNS/Domains/access when usign VPN

    I have an Widows 2012 R2 server.
    IT is always connected to a VPN
    I run IIS for a couple of internal websites (These are not internet facing).
    Most PCs on the network are permanently connected to a VPN.

    Recently I found that we have DNS leaks. Where the PCs local adapter is configured with the VPN's DNS servers we hit a transparent DNS Proxy run by the ISP. To fix this we use the openVPN directive block-outside-dns

    Unfortunately, this breaks access to the internal websites by name. Access by IP address works fine.

    Without block-outside-dns using //server/home works
    With block-outside-dns //server/home times out
    With blokc-outside-dns //192.168.x.x/home works.

    I'm hoping this is a IIS configuration issue.

    Any suggestions?
