Am I missing something? Any help will be much appreciated. Thanks

I would have the sympath like this

.sympath srv*c:\Symbols*http://msdl.microsoft.com/download/symbols;C:\inetpub\wwwroot\ProductsService\bin

You could probably have mismatched symbols. Here is a command which will help in diagnosing the symbol load problems !sym noisy
