After running WCF on my Vista laptop (IIS7) I needed to deploy the application on some Windows XP computers. Again some strange errors occurred:
[code:html]
Error Description: "This collection already contains an address with scheme http. There can be at most one address per scheme in this collection.
Parameter name: item"
[/code]
The problem is that WCF cannot handle more than one identity (host headers) per website. At first I configured IIS to have one HostHeader. That solution was just to dirty. So I kept on searching the internet.
You can fix this problem by adding prefix-key(s) in the baseAddressPrefixFilters section of the Web.Config:
[code:xml]
<system.serviceModel>
<serviceHostingEnvironment>
<baseAddressPrefixFilters>
<add prefix=”http://www.local.develop”/>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
</system.serviceModel>
[/code]
Hope this helps.

While playing with IIS 7 I accidental destroyed my IIS (XML) settings file. To fix this problem I copied the .XML from a colleague PC to mine. After this my IIS started giving a strange error:
HTTP Error 404.17 - Not Found - The requested content appears to be script and will not be served by the static file handler.
After a quick search I found out that I copied the .XML from a 32 bit PC to my 64 bit Vista and that all my Application Pools where now running on 64-bit. So my application stopped working because it's 32 bit.
To fix this problem go to IIS, right click your Application Pool and set the Enable 32-bit Applications to true.
