CRM Upgrade – Network name cannot be found error

When you follow the “lift and shift” upgrade method i.e. backup the old CRM database, restore it in the target environment and run deployment manager to import the organisation database, upgrade should be relatively easy. But, recently I experienced an issue that was such a pain to troubleshoot, I thought I will share this experience so that it will be helpful to others.

Below is the error I got when I import the organisation database using Deployment Manager.

Deployment Manager Error

This is what is captured in the deployment manager log (%AppData%\Roaming\Microsoft\MSCRM\Logs)

It looks like the database server name is wrong. But it is not. I used “Process Monitor” to troubleshoot the error. Here is what “Process Monitor” picked up.

Process Monitor Error

As you can see, the underlying error is a caused to lack of permissions to copy a dll file to a UNC path pointing to the database server.

Cause: McAfee Antivirus was blocking copy of any dlls through UNC path.

Resolution: Turn off “On Access Scanner” and “Access Protection” features of McAfee Antivirus during the organisation import.

In my case the KB article for SqlServerPathOverrides caused me to waste more time. I still had the same issue even after creating the network share, as McAfee was blocking all dll copy operations to UNC paths.
