关于动态crm 2011中联系人创建的一般SQL错误

Question

I've unregistered all plugins and deactivated all workflows for the contact entity and also there is nothing at the on save event of the contact entity in MS Dynamics CRM. Also, I've restarted all async services and even IIS. But still I am facing SQL Server Generic error. Here in the following is the log file of the error.

Update: Error Logging Details

This is normally caused by the Duplicate Detection system.

To disable this setting open you CRM then go to Settings -> System -> Data Management -> Duplicate Detection Settings
