I followed the steps above and get the following error message:
---------------------
Bing layer failed to load: Fault code: 401
Fault info: Unauthorized
Fault details: Access was denied. You may have entered your credentials incorrectly, or you might not have access to the requested resource or operation.
-------------------------
I did a cut/paste of the key from manager (arcgisserver 10). My confix.xml file has
<configuration>
<bing key="CUT/PASTE KEY"/>
as well as the layer tags under the basemaps tag.
Any idea what I'm doing wrong? I'm assuming it's not recognizing the key, but why? It came straight from arcgisserver as a cut/paste.
EDIT:
Never mind! I missed:
<!-- replace the following key with your own Bing key -->
in the config file initially. Works find now.
