I am working on a 4.61 site (long story short - we had the migration halted whilst we created new templates).   Anyway - the database is located at 10.0.0.13 so the web.config references to the SQL database need not change, but when I tried to Publish the site to 10.0.0.13 and host it with IIS, I get some strange behaviour. http://10.0.0.13:2001 or http://10.0.0.13:2001/ give the following message

Exception details: HttpException: The file '/en/default.aspx' does not exist.

Http status: 404 NotFound

Stack trace:

And if I go to IIS on 10.0.0.13 and right click + browse with IIS MMC, I get a 404 error saying /en/default.aspx cannot be found.

The web.config looks like this    (some omitted for brevity)

i would be grateful for any advice.  This is frustrating!
