Answer Posted / sagar
A User DSN is data connection created and owned by a single
user account. The connection and its configuration are no
longer valid when the user logs off.
System DSNs work for anyone using that system. For example,
no matter who logs onto the machine, system DSNs can be
seen by all users, and they are stored in the Registry in
the Local Machine section.
