Reference svcmap specified argument was out of the range of valid values

 this error occurs after deploying a WCF Service to IIS 6 which was referenced from Visual Studio 2008 with .NET Framework 3.5 SP1 and works perfectly in the local development environment. The server is a Windows Server 2003 with .NET Framework 3.5 without the SP1 installed. We solved the problem by installing 3.5 SP1.

Microsoft OLE DB Provider for ODBC Drivers error ’80004005′

[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

/2008/mission.asp, line 174

Notes: strange the error states no data source name found and no default driver specified. If you are certain your code is correct. Please contact your host and ensure the web folder has been set as a application. This resolved the error for me.
