Dynamics CRM 2011 Import Organization from different locale fails on SQLException

I'm struggling with a Dynamics CRM 2011 , when trying to import an existing organization - coming from a customer's Window Domain, not ours.

The Setup

Two servers.

• One windows server 2008 r2 x64 Standard (locale fr-FR) for the Front-end, WebApp and all
• One Windows server 2008 r2 x64 Enterprise (locale fr-FR) with SQL Server 2008 R2 Enterprise edition (locale fr-FR) for the Data and Report Tier

The imported organization came from an install with both Data Tier and App Tier on the same Windows 2008 Server (locale en-US)

The Web tier is at v5.0.9688.1045 , the Data Tier is at v.5.0.9688.1155 ( Update Rollup 2 )

The Error

The Database is recognized as a Dynamic CRM database, the users mapping proceeds, and the import process does most of the work. Most of because it seems to fail at the last moment.

Thanks to unlocalize.com : SQLException : The login already has an account under a different user name.

What I already tried to do - but didn't work

• Googling for the solution.
• Deactivating and deleting the starter database.
• Mapping the foreign domain AD users on completely new local domain AD user.

Thanks in advance for help

EDIT 1 : Added locale info, and corrected some inexact setup info

I've just phoned with Microsoft Support, and with its help I could solve this issue.

The Bug :

The problem here was a localization issue. My fr-FR Dynamic CRM Install tried to add a SQL user called "AUTORITE NT\SERVICE RESEAU" on the imported database while a "NT AUTHORITY\NETWORK SERVICE" user already existed. Both are in fact the same login account, that's why i had this problem.

The solution:

the offender here is "NT AUTHORITY\NETWORK SERVICE" or its localized name

On the database you want to import

• Delete offending schema
• Delete offending user
• Import again. It should work.
