I have a asp.net mvc 2 on .net 4 with code first entity framework data access.

When I deploy to one server it works beautifully, no prizes for guessing it doesnt work on the other…the message however I cannot understand

Attempt by method ‘System.Data.Entity.ModelConfiguration.Internal.Configuration.CodeFirstCachedMetadataWorkspace.GetProviderInvariantName(System.Data.Common.DbConnection)’ to access method ‘System.Data.Common.DbProviderServices.GetProviderFactory(System.Data.Common.DbConnection)’ failed.
