Problem when configuring multiple web services through https (2 web services give same output)

In our company we use a NAV5 SP1 database with a technical upgrade to NAV2009R2, so we can use web services. We have 3 different environments: Development, Test and Live.
For every environment we have setup a web service through https. The following guideline is used: http://www.archerpoint.com/blog/Posts/setting-ssl-web-services-nav-2009-r2-and-server-2008-r2
After processing the paragraph ‘Configure the server’s Access Control List and the Web Services Port’ from this guideline the following output for ‘netsh http show urlacl’ is shown:


To test the web services the following commands are used:
- https://<ip-address>:7047/NAV_Ontwikkel/WS/Services
- https://<ip-address>:7047/NAV_Test/WS/Services

The problem is both calls give the result from the database with server instance NAV_Test.
Can somebody give me a hint to solve this problem.

Thanks in advance.
