New MDS install. Getting Access Denied browsing to GettingStarted.aspx

I just finished going through the MDS setup process.  Verified web server and db server settings.  The first time I tried to browse to the new site,  I get the simple message "Access Denied".

I verified that the service account and windows group I am a member of, have access to the site.

In SQL Server Profiler, I can see just three lines which indicate success:

RPC:Completed exec sp_reset_connection .Net SqlClient Data Provider

Audit Login-- network protocol: TCP/IP

RPC:Completed

declare @p2 nvarchar(max) 

set @p2=N'3600'
exec [mdm].[udpSystemSettingGet] @SettingName=N'DatabaseTimeOut',@SettingValue=@p2 output
select @p2

So, why am I getting Access Denied?  What have I missed?
