Internal SOAP Processing Failure

When running web services through BizTalk either give ASPNET user access to the BizTalk management database, or impersonate the BizTalk services user in the web service's web.config. If impersonating the BizTalk services user, give access to C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files folder. These changes should solve the Internal SOAP Processing Failure error.
