Microsoft Dynamics CRM 4.0 – Importing Organization fails with “The connection’s state is closed”

Redeploying large databases can take a lot of time, I generally estimate 1 hour per gig of database size which has turned out to be a reasonable number. For example the most recent redeployment was 10 gig and took between 9 and 12 hours over the course of 3 re-deployments for testing and otherwise. However, with the larger databases you can run into server limitation which has resulted in KB 2003564. Its important to note that once the database has been redeployed some of the settings within the KB will need to be reversed, this is outlined within the article.
KB 2003564 Description
When you import a Microsoft Dynamics CRM 4.0 organization, you may experience a timeout or a hang in the MMC console window hosting the Microsoft Dynamics CRM Deployment Manager.
The Microsoft CRM Deployment Manager window may show up as a white screen during this time and Windows Task Manager will show the program “Deployment Manager” as “Not Responding”. This may even happen if you have increased the OLEDBTimeout setting for Microsoft Dynamics CRM 4.0 to a value greater than when the error was experienced.
If you enable platform tracing, using the steps in KB 907490, How to enable tracing in Microsoft Dynamics CRM, http://support.microsoft.com/default.aspx?scid=kb;EN-US;907490 , you will see an error like the following in the platform trace files (Note that the default log for Importing an organization will be located by default in the %appdata%\Microsoft\MSCRM\Logs\Import.log file for the user who installed Microsoft Dynamics CRM 4.0.
