Unable to connect to .NET 4.0 WCF web service within Flash Builder Burrito

I'm trying to connect to a very s开发者_Go百科imple .NET WCF web service (created in .NET 4.0) within Flash Builder Burrito and the process hangs on "Introspecting the service". I get no errors -- it just hangs. The web service is on my local network, although not on my local machine. Any ideas??

FB finds something wrong in service metadata and trying to check with www.w3.org You need to block it from that either by disconnecting from network (disable adapter or take out network plug). Or in c:\windows\system32\drivers\etc .... find hosts. text file (without extension) and add an entry at the bottom: 0.0.0.0 www.w3.org make sure to have new line at end.
