I just installed SDP 9004 on server in our envrionement for testing purpose since our prod SDP is still 8125 I believe.
Anyway, I installed it and it works fine with our DB imported and everything. My problem is my website can't be accessed from our network, it only work locally on my server.
Now if go on my prod server is look in ISS I see the default website pointing to an index.html which is SDP home page but on my testing instance I can't locate that index.html page or the folder "sites" that I have in prod.
