Every Microsoft SQL Server™ service has a user context. A user context is a set of Registry entries that includes the definitions of the ODBC data sources for the user. The user context is provided by the username under which the SQL Server is running.
For example, if the server is running under the system account user context, the DSNs that are returned will all be system DSNs that are associated with the system account. If the server is running under a private user account, only the DSNs defined for that user’s private account are returned.
Only members of the sysadmin fixed server role can execute sp_enumdsn.
