Applies to: All versions of Centrify Deployment Manager

Problem:
When the AD user's "Application Data" folder is located on a network share. For example:
1. The AD user is using roaming user profiles or,
2. The "Folder Redirection" group policy has been enabled to redirect the AD user's "Application Data" folder to a network share.
 

An error message "Failed to load data from datastore" is shown when opening Centrify Deployment Manager (DM) and you can find the following message from the debug log:

There is a file sharing violation. A different process might be using the file. [ \\servername\folders$\TVNS0000\Application Data\Centrify\DeploymentManager\datastore.sdf ]

Cause:
After the DM had been installed, a small Microsoft SQL Server Compact Edition database is embedded into the MMC application. The database serves as a repository for the machine and environment information that the Deployment Manager gathers. However, Microsoft SQL Server Compact doesn't support multiple concurrent connections to a database file located on a network share and will create an exclusive lock on databases open on network shares.

Workaround:
It is suggested to install DM on a dedicated machine and configure the AD user using local user profiles.
