How to configure MS Loopback Adapter in Windows 7

Question

Hello all,
I installed SAP NetWeaver 7.02 SP06 ABAP Trial Version mainly to teach myself some
WebDynpro Programming for ABAP. Unfortunately this does not work correctly.
I created a View in a Web Dynpro Component and the Layout Preview does not work.
I activated the services suggested in
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/30129979-011c-2e10-fb9b-a60e0d704c1d&overridelayout=true
and did use the report RSICF_SERVICE_ACTIVATION with the variants
WEB DYNPRO ABAP
WEB DYNPRO ABAP DESIGN TIME
WEB DYNPRO ABAP TEST APPS.
In Addition I have set the FQDN as described in the document. I think the problem is the
MS Loopback Adapter. It is displayed with "No connection" in the Network and Sharing Center. I have no idea
how to change this. I have set the IP Adress to the on suggested in the Installation Instructions (10.10.0.10, Subnet-Mask 255.255.255.0) but the Loopback Adapter is displayed with no connection.
If I call a test webdynpro with the Hostname "localhost" it does work, so I think the webserver is running.
Any ideas ?
How do I set up the MS Loopback adapter under Windows 7 correctly ?
Thank you in advance,
Axel

Hi Axel,
Now that you know your local network works correctly for a computer not connected to internet or intranet, you have to do this:
1- For "No Connection" error (it is not necessary for the sap system to work), it's normal.
Create a local intranet with a 2nd computer if possible and make a configuration for home network after you will see "Connected"
2-Use of Pc hostname
You must configure the "profile parameters" by using transaction RZ10 and activate services (it's not easy, you have to take your time).
3- Webdynpro
To see the result of the webdynpro appli, you may know that not all web browser versions are compatible. The recent browsers don't work, use iexplorer8 or mozilla but not google ==> you will solve the problem of "timeout".
After that:
Activate the "internet communication framework" by using Transaction SICF. It takes you to "Maintain Services" and then fill Hierarchy Type ==>services, execute to reach at this step:
default_host/sap/bc/gui and icf ( If you've installed sap java, you will see both sap and sap_java)
do a mouse right click and select "Activate Service" and choose activate all.
You can now test the sample via web browser by using locahost.
Best regards.
