I have two salesforce accounts, our production account, and our developer account. When I export the exnterprise.xml file from the developer account and add it to VS 2005 as a web reference all works.

When I download the enterprise.xml file from production and add as a web reference it fails with the following error:

The Custom tool MSDiscoCodeGenerator Failed. Unable to import binding "SoapBinding" from namespace "urn:enterprise.soap.sforce.com".

Any ideas? Why is this failing, I cannot see many differences between the file headers.
