I have written some time ago a blog post which have a workaround with removing http headers in iis.
Now I found in documentation prefixfilters which allow the use of ado.net dataservice with multiple host headers on website. There must be some setting in web.config like
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" >
<baseAddressPrefixFilters>
<add prefix="http://www.vsone.de"/>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
</system.serviceModel>
</configuration>
No I run in second problem.
IIS specified authentication schemes 'Basic, Anonymous', but the binding only supports specification of exactly one authentication scheme.
OK- it’s easy to change that in IIS. But what's about authenticated access e.g. for Frontpage server extensions?
Still looking….
Next I got a error message
Request Error
The server encountered an error processing the request. See server logs for more details
aha-mhh- which logs- where, WTF?
I found a sloution to display the full error within browser. You have to add in service metadata.

Now I have the next error:

Reason now is that I developed with a Silverlight 2 project. And destination is a website. Connection String must be diffrent.
