How to get 10.0.2 to work on Windows with ISS and SQL Server

I have installed 10.0.2 on Windows with a SQL Server back end. When I went through the install I got to the last screen which shows:

Creating Sugar configuration file (config.php)

Begin rebuilding web.config

Rebuilding UTF-8 document

Rebuilding configuration element

Rebuilding system.webServer element

Rebuilding rewrite element

Rebuilding caching element

Rebuilding staticContent element

web.config is rebuilt

     Creating default scheduler jobs...   done

Populating the database tables with demo data (this may take a little while)

The setup of Sugar 10.0.2 is now complete!
Total time: 143.10731101036 seconds.
Approximate memory used: 120144888 bytes.

So that appears to have work however when I try to connect to the logon page in IE 11 I get "Loading ....." and in ie I get an internal server error 500 when looking for page :-

172.20.6.5/.../public

I checked my sugracrm2 folder for a rest folder which does not exist. Should this have been created as part of the installation or have I missed a step ?

Thanks,

Richard
